Introducing Polska Antropologia Fizyczna on FB

16 Nov

If you are anything like me, you will have a large pile a books by your bedside either waiting to be read or already partially digested.  And sometimes this dirty habit of reading too much will catch up with you.  At the moment I’ve somehow managed to buy, borrow or otherwise lend a mountain of books that will last me through a cold and dark winter.  I’m not particularly sure why I thought starting five (non-academic) books at once was a good idea!  I’ve recently added one more in the form of Knüsel & Smith’s excellent 2014 The Routledge Handbook of the Bioarchaeology of Human Conflict, a volume I’ve long wanted to read but is frankly too expensive to buy.

A stellar volume of bioarchaeological research for the low, low price of £175.00 in hardback or £142.20 for an ebook version. Image courtesy of Routledge.

Where did I find this fine volume, I hear you ask? Whilst browsing the awesome Polska Antropologia Fizyczna (PAF) Facebook group (don’t tell the publishers though!).  PAF is a group set up by Oskar Nowak, who is an assistant professor at the Institute of Anthropology at Adam Mickiewicz University in Poznan, Poland, dedicated to sharing anthropological research online and to fostering an active research community.  I love browsing this FB group as there are always links to open access articles on a wide variety of research topics, including bioarchaeology and related disciplines (osteoarchaeology, palaeopathology, etc.).  Like a number of FB groups, such as BAJR – UK Archaeology, Palaeopathology and Council for British Archaeology, the PAF are a pretty active community, so it is worth checking out.

But for now, if you need me, I’ll be buried under a pile of books on Scandinavian, Soviet and post-Soviet literature and history!

Reflection During a Day of Skeletal Processing

8 Feb

I have a day off from my normal job and I find myself carefully wet sieving the cremated remains of a suspected Romano-British individual in the processing room at the local unit, but I’m not alone here.  Instead I’m surrounded by recently excavated Anglo-Saxon remains drying slowly on paper towels, organised in numerous plastic trays on various shelves to my side and up above me.  In each tray there is a plastic zip bag, the site code and context number inked on for identification purpose and later site reconstruction.  By taking the right femoral head and neck (upper thigh) as an identifier of the minimum number of individuals (MNI), I count at least six individuals represented in the new assemblage, although there are a few trays I cannot quite see and as I am not here to look at them I do not uncover them.  A quick look at the morphology (size and shape) of the individual skeletal elements is enough to see that, demographically speaking, adults and non-adults are represented in the assemblage.

Browsing the mandibles (lower jaw) that are present I can see a few without the 3rd molar fully erupted, one or two lying in crypts waiting to reach up for the shaft of light from the outside world that would never come.  Another mandible has the majority of the teeth present, including the 1st, 2nd and 3rd molars in each half, but it displays severe enamel wear of the crowns of the teeth (the occlusal or biting surface).  This is indicative of a rough diet and probable middle to advanced adult age.  The fact that most of the teeth are present suggest that the individual wasn’t too old though, as tooth loss is strongly correlated to increasing age for humans.

I turn my attention back to the cremated remains.  These are something of a mystery having looked at the context sheets dating from the excavation itself.  There is evidence for cremated non-human remains, likely to be bovine (cow to you and me) as there are a few distinctive teeth included in the bags in an associated context found near the cremated remains that I’m now processing, which itself has been bulk sampled at 100%.  A proper look through the sieved cremated material, which has been processed in accordance with the British Association of Biological Anthropology and Osteoarchaeology guidelines, will have to wait though as they need to dry over the next few days, ideally for another few days after too.  Once dry I can go through each fraction sieved (10mm, 6mm, 2mm) and sort as human and non-human, before identifying specific osteological features and assigning the fragments to either skull, limb, or trunk sections of the skeleton.

As I think about this I remember that I must complete this human osteology report soon.

For many people the thought of touching or analyzing human remains is too much, that in many minds remains are parceled off to the medical realm or are hurried to the cemetery to be removed out of sight.  In reality though we are often surrounded by human remains, though we may not always know it and may not always want to know it.  In archaeology the skeletal remains of humans are often the only direct biological matter to survive of individuals and past populations.  They can encode and preserve a lot of information on biological matters and past cultural practices.  This has been steadily recognized within the past century as osteological methodologies are refined for accuracy and new technology is applied in novel approaches to the remains unearthed.  One of the prime concerns for any bioarchaeologist or human osteologist is that ethical codes and guidelines are adhered to, with the relevant legal permits acquired as appropriate.  As I glance upon the presumed Anglo-Saxon remains I remember that these too were unexpected finds by the construction workers, I briefly wonder how they felt and what they thought on seeing them for the first time.

Anyhow, back to processing the cremation and to thinking about writing the report.

It is pretty interesting as although I’ve part-processed cremations within urns before, with careful micro-excavation spit by spit, I’ve never fully processed a cremation to completion.  Whether these cremated remains represent human skeletal material, as the field notes state, remains a different matter though and it is one I am eager to solve…

Further Learning

  • The British Association of Biological Anthropology and Osteoarchaeology (BABAO) promotes the study of understanding the ‘physical development of the human species from the past to the present’.  As an association they provide research grants for projects in which all members of BABAO are eligible, as well as offering prizes for presentations and posters in their annual conference, which is held in the United Kingdom.  I fully recommend attending and taking part if you are associated with any relevant field.

Upcoming Conference: ‘Skeletons, Stories & Social Bodies’ at the University of Southampton, March 2017

25 Nov

An upcoming interdisciplinary conference entitled Skeletons, Stories, and Social Bodies (SSSB) aims to cover a wide range of topics relating to human anatomy and death.  Taking place at the University of Southampton from Friday 24th March to Sunday 26th March 2017, the conference organizers are keen for students, early career researchers and commercial archaeologists and bioarchaeologists to contribute as appropriate.  The keynote speakers for the conference have recently been confirmed as Dr Heather Bonney, the collections manager of anthropology and a practicing forensic anthropologist at the Natural History Museum, London, and Professor Caroline Wilkinson, a forensic anthropologist from FaceLab at the Liverpool John Moores University who specializes in the forensic reconstruction of faces from both forensic and historical contexts.

Alongside the usual presentations and a conference dinner on the Saturday evening, there is also the opportunity to take part in a number of workshops by the Centre for Learning Anatomical Sciences and art exhibitions on the Sunday.  The five optional workshops include the chance to learn about bioarchaeology, or to attend workshops investigation the scent of death, grief demystified and or an introduction to the Anatomical Sciences laboratory among other topics.  Please note that conference delegates will only have the option to sign up for two of the five workshops due to limited places.

The price for the conference has now been confirmed – please see the conference homepage for the range of prices available.  For the full event attendance the price is set at £65 (student) to £85 (waged), costing a total of £115 if registration is late, but individual day rates are also available.  As such it is advised that anybody interested book before Tuesday 31st January 2017 for early bird registration, whilst late registration is available from the 1st February until the 20th February 2017, which is likely to cost more.  Furthermore there are student bursaries are available for undergraduate and postgraduate students.  Please see here for further details and the conditions stipulated.

Topics for Consideration

As this is a very wide-ranging conference the topic of the talks submitted can fit into several categories.  I’d imagine it would depend on the number of the topics received as to how the sessions themselves are organized over the three-day length of the conference.  These topics include, but are certainly not limited to, the following subjects:

1) History of anatomy & dissection
2) Dissections, prosections and technology: replacing cadavers?
3) Death in the modern age
4) Ethics of display of human remains
5) Funerary practices through the ages
6) Disability and disease: archaeological and medical
7) Forensic investigation and approaches
8) Death on the big screen: television and film
9) Lifecourse and osteobiographies
10) Morphology and evolutionary anatomy
11) The body social

Please note that this information was taken from the SSSB 2017 website directly.  From this quick overview it certainly looks like the conference will be a great mix of topics from both historic (and hopefully prehistoric) and modern vantage points, where the humanities meets the sciences in discussing the body, death and the funerary and social treatment of the dead.  Personally, having had the opportunity to dissect the musculoskeletal anatomy of a donated cadaver during my Masters degree in Human Osteology and Funerary Archaeology at the University of Sheffield, I very much appreciate the importance of understanding anatomy within a osteoarchaeological context.  The archaeological and cultural context are of considerable and prime importance, but the body too must be understood if we are to make sense of both past individuals and populations and their lifestyle.

Presentation Style: Select your Poison

The call for papers deadline is Friday 16th December (now passed), so there is not much time left to submit an abstract for any of the topics above.  Submissions are sought for podium, poster and Pecha Kucha presentations with abstracts of no more than 300 words accepted which outline the topic and the aim of the presentation.  As this is an interdisciplinary conference there is a great opportunity to engage with researchers and students who may not normally come into contact with your area of interest and thus may provide stimulating and thought-provoking comments, or new research connections and avenues of exploration.

The conference gears up for March 2017. Image credit: SSSB 2017 website.

This is also the first time I have seen the mention, or use of, the Pecha Kucha 20×20 method within a conference setting and I have to say I am pretty excited to learn more about it and to see it in action.  The method involves the use of 20 slides with a 20 second exposure for each slide, therefore limiting the presentation to a total of 6 minutes and 40 seconds ideally.  The express aim of it is for the information presented to be precise, concise and short.  This is often achieved by limiting word use on-screen and instead relying on graphs, diagrams and images to convey the vocal component of the talk.  Variations are known where feedback is given immediately after the talk, which increase audience participation, knowledge sink and activity for all involved.

Further Information

  • One of the individuals on the organizing committee for this conference, PhD candidate Sammy Field, has her own blog at Beauty in the Bones.  Check it out for comprehensive posts on a variety of osteological interests.  There is also a great resource page which lists current British human osteological collections and the chronological span of the populations under curation at each institution.  Osteological collections are a vital resource for bioarchaeologists, who analyse human remains in order to understand past lifeways and populations.
  • Readers remember, if you know of any major international or United Kingdom based bioarchaeology, funerary archaeology, or osteological conferences coming up in 2017, then please do drop me a message to either include them in this post or for me to mention them in a brand new post at a later date!

Publication of New Developments in the Bioarchaeology of Care: Further Case Studies and Expanded Theory

28 Oct

As I have recently discussed on a blog post about recently published or forthcoming bioarchaeology books, I too have had a book chapter published in a new edited volume for the Bioarchaeology and Social Theory series, as produced by Springer.  The volume is titled New Developments in the Bioarchaeology of Care: Further Case Studies and Expanded Theory (£82.00 hardback or £64.99 ebook) and it is edited by Lorna Tilley and Alecia A. Shrenk.  The volume presents new research regarding the bioarchaeological evidence for care-provision in the archaeological record.  Using the associated Index of Care online tool, bioarchaeological researchers can utilize the four-stage case study approach to analyze and evaluate the evidence for care-provision for individuals in the archaeological record who display severe physical impairment likely to result in a life-limiting disability, or to result in a sustained debilitating condition which limits involvement in normal, everyday activities.  (For further information see a full book description below).

In short, my chapter investigates the public reception and engagement of the bioarchaeology of care theory and methodology as proposed by Lorna Tilley in a slew of recent publications (see bibliography).  As an inherent part of this the chapter discusses the ethical dimensions within the approach used for analyzing physically impaired individuals in the archaeological record, and the potential evidence of care-provision as seen on the osteological remains of the individual and contextual archaeological information.  Proceeding this is a walk-through of traditional and digital media formats, presented to provide a contextual background for the communication of the theory and methodology which is subsequently followed by two bioarchaeology of care case studies, Man Bac 9 from Neolithic Vietnam and Romito 2 from Upper Palaeolithic Italy, which help to summarize the public perception and importance of the research conducted to date within this new area of investigation and analysis.  In the conclusion best practice advice is provided for researchers conducting education outreach with regards to publicizing the bioarchaeology of care research and its results via both traditional and digital media formats.

The following information is taken from the Springer press release (and is used with the permission of Lorna Tilley) regarding the volume, both its aims and its content:

Book Overview

Only in the last five years has the topic of health-related care found acceptance as legitimate subject matter for archaeology.  In 2011, a case study-based ‘bioarchaeology of care’, designed to provide a framework for identifying, analysing and interpreting evidence for likely disability and associated care response, was proposed; the approach generated academic and wider public interest, and from this time on it has continued to evolve as bioarchaeologists apply it to cases of likely caregiving and broader theoretical questions of care provision within their areas of specialisation.’

New Developments in the Bioarchaeology of Care: Further Case Studies and Extended Theory 

The volume ‘marks an important milestone in this evolutionary process.  Its origins lie in a symposium entitled ‘Building a Bioarchaeology of Care’, held during the Society for American Archaeology 2015 annual meeting, which brought together an international, cross-disciplinary group of scholars to explore this theme.  This book contains 19 chapters, most based on symposium presentations, the first substantive chapter providing an overview of the bioarchaeology of care methodology and last situating the bioarchaeology of care approach, and the chapters in this book in particular, within the discipline of bioarchaeology more generally.  The 16 chapters that comprise the core of this volume offer content which is always original, often methodologically innovative, and frequently challenging, and are organised under three headings.

In the first section, Case studies: applying and adapting the bioarchaeology of care methodology, Chapters 2-9 focus primarily on the care given to one or more individuals who experienced (variously) a congenital disorder, acquired disease, accidental or intentional injury and who date to prehistory (Bronze Age, United Arab Emirates), through later Pre-Columbian (southern United Sates and Peru) and Mediaeval periods (United Kingdom and Poland), to relatively modern times (late 18th century London).  These chapters also contribute to bioarchaeology of care theory, however, because each one, in some way, has implications for how we conceptualise past caregiving or for how we might improve current research methods.

In the second section, New directions for bioarchaeology of care research, Chapters 10-16 explore alternative perspectives for illuminating past health related care behaviours.  Respectively, they address the scope for applying the bioarchaeology of care methodology to mummified remains; the potential for research into past caregiving to focus on demographic sectors of the population which are often overlooked – specifically children and the aged; the prospects for acknowledging psychological, spiritual and/or emotional forms of support in bioarchaeology of care studies; the modification of the bioarchaeology of care model to allow an assessment of institutional healthcare efficacy at both an individual and a population level; the development of a biocultural model for examining the origins of health-related caregiving; and the potential relevance for bioarchaeology of care studies of an online application supporting research into clinical and social implications of living with disease.

In the third section, Ethics and accountability in the bioarchaeology of care, Chapter 17 interrogates the principles, assumptions, values and beliefs that are likely to influence carriage of bioarchaeology of care research, and Chapter 18 considers ethical responsibilities involved in communicating bioarchaeology of care research findings in the public domain, and discusses some practical ideas for information-sharing.’

The volume isn’t cheap by any stretch of the imagination, so if you are a student or a researcher interested in this topic I highly recommend that you advise your university or institution library to order a copy.  If you are a member of the public I recommend again that you use your local library and order a copy in or use the inter-library loan system in order to source a copy of the volume.  Alternatively individual authors of the chapters may upload their sections of the volume to their own respective academic social media websites, such as on ResearchGate or Academia.edu, if they have a profile.  For instance you can read my chapter here.  It also always worth emailing the researcher in question if you are interested in accessing their work and are unable to locate the writing online.  From a quick internet search it seems Google Books also has the book scanned and it is partially available here.

Guest Post: An Introduction to Artificial Cranial Deformation from the Great Migration Period in Europe by Maja Miljević

17 Oct

Maja Miljević is currently an undergraduate student studying archaeology at the Faculty of Philosophy, University of Belgrade, Serbia.  Her main interest is in physical anthropology, with a research interest in prehistoric archaeology.  Maja has had previous experience of analysing human skeletal remains as a part of a faculty module in the Laboratory for Bioarchaeology, at the University of Belgrade, where she took part in the osteological analysis of a number of individuals dating from numerous Mesolithic and Neolithic archaeological sites located in Eastern and Central Serbia.


Introduction

Intentional or artificial cranial deformation has been long known through human history, even though many articles have been published during recent years which have been focused on more earlier periods of prehistory.  In order to highlight historic cases that I present this short article on intentional cranial deformations from the European Great Migration period (3rd to 8th centuries AD), with a particular focus on the 5th to 6th centuries AD in modern-day Serbia and modern-day Hungary, which highlights the practices of cultural identification in these cultures in this turbulent period.

Intentional Cranial Modifications

Intentional cranial modification has been documented throughout world prehistory and history across a number of distinct geographic areas and cultural groups.  They date back to the Late Paleolithic period (1) at the earliest example so far recovered (Molnar et al. 2014).  The most well-known cranial deformations are those from the Maya culture in modern-day Mexico in the first half of the 2nd millennium AD, various South American prehistoric cultures, and from Ancient Egyptian populations of the 18th dynasty.

Cranial bones can be modified easily in the younger population, since their cranial bones are soft and elastic.  Artificial cranial modification is largely achieved through the binding of the head, using boards, straps, cords or pads (Hakenbeck 2009).  The deforming apparatus is used for a few days up to six months, or sometimes even longer ranging from 3 to 5 years of use.  Cranial deformities of this kind are done as the results of cultural practice and religious beliefs.  The main goal of this practice is to be distinguished from others within the population and to indicate special social status (White et al. 2012; Miladinović-Radmilović 2012).

Intentional Cranial Deformation Types

There are five basic types and areas of artificial cranial deformation (abbreviated to ACD where appropriate) and they often involve the use of boards and pads to achieve their distinctive styles:

a) Lambdoid
b) Occipital
c) Fronto- vertico occipital
d) Parallelo-fronto occipital
e) Annular deformation

As seen above artificial cranial deformations includes various or individual regions of the skull where pressure can be applied, such as the occipital, frontal regions, or both together, the mastoid region, and finally the region just above the insertion of the nuchal ligament on the occipital bone.  These are largely referred to as tabular deformations.  As well as this there is another type practiced that included bandaging, with wrapping materials, called annular deformation, around the full circumference of the skull, which is also performed in early childhood (Miladinović-Radmilović 2012; Molnar et al. 2014; Ortner, Putschar 1981).

Origin in Barbarian World

Origin of this practice among the barbarian world probably started with Sarmatians, Huns and continued with the Germanic tribes (Alan, Goths, Gepids), as the practice was spread across Europe in the mid to late 1st millennium AD.  The practice of skull modification had probably originated in the central Eurasian steppes in the first century AD and then may have been brought to central Europe with nomadic people and various tribal units (Mrkobrad 1980; Hakenbeck 2009).

Thanks to this culturally mediated osteological difference in the skeletal remains in the Great Migration period, it is a key indicator for understanding the process of said migration during the Middle Ages in the archaeological record in this locality.  Not only did they just bury their dead in either settlements or necropolises, it is also likely proof that they had intentions to stay and live there, as demonstrated by the term from anthropology – acculturation (2); they lived in the same houses, used the same tools, and probably dressed like, or as similar to, the Romans themselves.  As it is seen in an example from the Gradina na Jelici site where three juveniles were buried in two basilicas, all with clear intentional deformations and grave goods that are attributed to Germanic tribes, either the Gepids or Langobards  (also known as the Lombards)(Mилинковић 2010).

In Southeast Serbia there is a necropolis site called Viminacium-Više Groblja, where a total of 94 buried individuals have been excavated and in which 31 individuals exhibit artificial cranial deformation attributed to the Gepids.  The Gepids were closely associated to the Goths due to their cultural similarity.  The reconstruction of a Gepid woman was produced and helped to highlight how her cranium was viewed in life and how her hair was tied with organic material, which probably mimicked the wrappings used to shape her head during infancy (Mилинковић 1998; Микић 1993).

Reconstruction of a Gepid woman demonstrating ACD. The reconstruction is based on an individual from the site of Viminacium, a Roman fort dating from the 1st century AD, located in Serbia which was overran by the Huns in the 5th century AD.  The site was rebuilt by Justinian but destroyed completely by the Slavs in the 6th century AD. Image credit: Mикић 1993.

According to Mikić (1985), two female skulls have also been discovered with artificial cranial deformations dating from the Great Migration period in Pančevo.  Modification was probably already visible in the second decade of life and was produced by using tight wrapping materials around the frontal, parietal and occipital bones of the cranium.  There was not only one wrapping material used that produced an annular deformation to the skull, but it was one used long enough in order to produce a high pressure effect to the skull as seen in the x-ray below.

The first skull, as viewed using an x-ray from a lateral aspect, highlighting the distinctive pressurized cranial deformation. Image credit: Mikić 1985.

As for second skull, modification was carried out a little bit differently in this instance.  Wrapping material was also used, but with a heavy burden, which gave the female individual a distinctive saddle recess as demonstrated on the parietal bones, as seen on the x-ray below.

Besides those sites, another interesting archaeological site where there is evidence of this artificial deformation is in Sirmium, a major Roman and barbarian site in Serbia, where there is one male-assigned skull described with a deformation.  It may be possible that there are more buried individuals that belong to Germanic tribes exhibiting ACD.

So, it is obvious that they were a probable leader or someone who wanted to be distinguished from others as chosen by the individuals who carried out the artificial deformation on the infant (Miladinović-Radmilović 2012).

6-reconstruction-of-skull-in-sirmium-after-miladinovic-radmilovic-picture-6

Reconstruction of a skull from Sirmium, Serbia, described above which highlights the method used to bind the cranial bones in this manner. Sirmium was a populous settlement first founded by Illyrians and Celts and subsequently become a Roman city. In the 5th century AD the city was taken by the Huns and then by the Goths and Gepids. Image credit: Miladinović-Radmilović 2012.

In Hungary itself we have a good example of a number of artificial cranial deformations, 9 individuals exactly who display this feature, from the Hun-Germanic period, which can help us to see that there is no difference in sex as both males and females were a part of this practice or at least subjected to it (Molnar et al. 2014).

From an anthropological point of view we need to ask how bad can the physical effects on the individual be?

We know that brain is a complex organ and that any modification or alternation to either it or the cranium may cause physical and behavioral changes in normal cerebral function.  If there is a high degree of deformation it may have influence in vision, worsening hearing ability or even cause epilepsy, depending on what type of artificial cranial deformation is used (O’Brien et al. 2013; Mrkobrad 1980).  Intentional cranial deformation may disrupt the normal closure time of the cranial sutures or produce minor effects like the increase of wormian bones in the lambdoid suture, which in life would be asymptomatic (Miladinović-Radmilović 2012).

Conclusion

As we have seen in few historic examples from Serbia and Hungary above, this cultural practice did not stop with prehistoric people and cultures as it was carried out across the globe, including during periods of great migrations.  It is interesting that it had a great influence on the barbarian people and their leaders of this period, and that it continued to be practiced after they had conquered their enemy tribes or warring nations.  It may be hypothesized that they still wanted to be seen differently or to be seen as superior both within and outside their own cultural group.  Unfortunately intentional cranial deformations probably stopped in the Balkans with arrival of Avarians, around the 6th century AD, although the practice still continues today within a modern medical environment.

Notes

1. Late Paleolithic (Stone Age) period goes back from some 40,000 to 10,000 years before present.

2. Acculturation is cultural modification of an individual, group, or people by adopting to or borrowing traits from another culture.

There was something comforting about a strangers dog looking up at me with unadorned glee at my open car door, waiting to be either patted on the head or to be fed a treat (perhaps both if they are lucky) I thought, as the car seemed to drag me into the parking space at work.  Earlier in the day I had stopped at a nearby nature reserve to break the journey in half in order to get some fresh air before the back shift started at the office.  To see the leaves dancing in the wind, to feel the sun on my skin; to know that there is beauty in the scenes where we are not the main actors but merely the passive observers.  I took out my notebook and scratched a few words into its carefully kept pages.  Today was going to be a good day.

Once parked up at work, and upon opening the door a fraction, my eyes spotted a fragment of bone on the tarmac.  One, two, perhaps three pieces?  One solid chunk and two small slithers of bone, the physical remnant of a body dispersed.  The larger chunk grabbed my more immediate interest and I stood up, leaned over and picked it up and carefully turned it over in my hands.  As I expected it was not human, but it was definitely from a mammal.  I chuckled to myself thinking it was a gift from the osteological gods.

Based on a quick morphological assessment it seemed to be a left distal humerus fragment (or, more simply, the top part of the elbow), as I recognised both the posterior olecranon fossa and the anterior coronoid fossa with their familiar shapes.  I also noted the slight ridge of bone that would have led to the medial epicondyle where it not heavily abraded.  Most of the articular surface of the trochlea survived although there were fragments abraded or chipped off either side of this.  Some of these minor breaks were clearly recent, the largest break had exposed a brilliant white patch of the dense cortical and honeycomb-like trabecular bone in clear contrast to the grayer surface that surrounded the broken area.  Still clearly visible, but largely fused, was the posterior line between the metaphysis and distal epiphysis indicating that the animal had not quite reached full adult growth, or skeletal maturity.  There was also a distinct clear transverse saw cut through the full shaft of the distal metaphysis, which indicated that the animal had likely been butchered or processed in some way.

Based on size alone it likely belonged to the Ovis or Capra genera, that is either a sheep or a goat.  There is the possibility that it could belong to the Sus genus, a pig perhaps, as they can be awfully similar in shape and size, particularly if they have not reached full skeletal maturity.  Zooarchaeologists, those who study the skeletal remains of animals from archaeological contexts, often pair sheep and goat together as it can be exceptionally tough to differentiate those two species from fragmented or isolated skeletal remains.  I could see immediately that the bone was not fresh, that the ashen tone indicated that it had likely spent time being bleached by the sun in the open air.

I knew that even though the industrial estate seemed nice enough, with the gleaming glass paneled Art Deco offices and funky design logos that adorn the signage boards, that behind the lush bushes and full trees that lined one side of the main avenue there was likely a rubbish tip of some description bordering it.  A dump that gathered all of the waste of modern life together to be compacted and squashed, to be buried beyond sight rather than to be dispersed invisibly into the sea or rivers as effluent is.  I had suspected this and wondered if this is where the bone had come from, carried perhaps in the beak of one of the numerous European herring gulls (Larus argentatus) that frequent the area.  They can be seen at all hours, chasing one another on the air currents or taking part in great aerial feats of imaginary bombardments over the great length of the industrial estate.

I’d come across bleached bone fragments before in such settings where gulls in particular rested and squawked at one another.  Still, it was interesting to see a few fragments of bone and to be able to identify and side which part of the skeleton they represented.  The material was clearly modern, even if sun bleached, and likely represented the fragments from waste sources, scattered by the combined action of animals and natural processes.  The bones had long ago lost their original context, had long ago lost even the rest of the body in which in life they were once a part of.  They could, though, still tells us something about the age of the individual that they represented, the likely size and the probable butchery of their body too.

Later on in the week, a few days after having discovered the bone fragment at work and when the weather had noticeably taken a turn for the better, I find myself happily sat outside in the back garden at home taking it in turns to read and to write.  But I am not alone out here.  I am joined by feathered friends that we keep in a coop towards the bottom of the garden, the three unnamed domesticated hens (Gallus gallus domesticus) that make their home here as we collect their eggs; they are a subspecies of the Red Junglefowl (Gallus gallus) who range over Southeast Asia and from which each domesticated chicken can trace its origin from.  The chickens in this garden are of the Gingernut Ranger type, a friendly, inquisitive and distinctive breed which are well-noted to be friendly and are always keen to peck, dig and generally explore the garden in search of hidden insects.  They also react quite joyfully to owners bringing scraps of food as daily treats.  The chickens are only unnamed because they are so similar-looking to one another, however we can easily tell them apart by their distinct personalities and social identities.

For instance, one of the chickens is remarkably independent and unrelentingly curious about the garden and any unusual sights or sounds therein.  She will be one of the first to peck and prod each section if we allow them into the garden or into an enclosure that we sometimes extend onto the grass via the use of spare chicken wire.  Furthermore, if she has the chance to, she’ll be the first to crouch down and take a flying jump out of said enclosure to scurry around in the undergrowth that lies temptingly out of the reach of the makeshift pen.  (I can only imagine the terror the bugs must feel on seeing this incessant eater appear in their midst).

The other two often keep together, but invariably follow the more independent chicken once it has taken flight. As they push their heads repeatedly through the wire to see where their fellow hen has gone their soft fleshy combs ping back and forth, a harbinger of their impending flight for freedom.  Truly it is a joy to look after these beasts, to watch them rake into the freshly upturned soil with their tyrannosaur-like claws, methodically working the soil searching for sustenance and then move forward once they have cleaned the section of life.  I wonder, briefly, if this is perhaps a new approach to tackling trowelling back on archaeological digs.  Again I chuckle at this flight of fancy and gently my thoughts return back to the fragment of bone found at work, wondering where the animal had originated from.

It was in this environment, watching the chickens explore the delights that the garden had to offer and intermittently reading Philip Hoare’s delightful 2013 memoir The Sea Inside, that I remembered the odds and sods collection of non-human skeletal material that I kept from various random chance occurrences.  Within this small collection were the skeletal remains of a shoulder of mutton meal that my family had eaten one Sunday afternoon.  The remains, cleaned of any surviving muscles, ligaments and tendons by knife, were slowly boiled in water over the course of an afternoon to further remove any remaining soft tissue.  It isn’t a perfect bone cleaning method though, and I’d recommend you read the blogs mentioned below for better tips on animal skeletal preparation.  What remained after a number of hours though were gleaming white bones; the complete humerus, radius and ulna bones of a sheep which could perfectly articulate together.  Perfect and whole examples to use as comparative osteological material in order to compare the distal humerus fragment against for both size and morphological differences and similarities.

I also remembered that in one of these pots outside I had buried the skeletal remains of an ox tail, again the leftovers of a family meal that had taken place some time ago.  This was, I think, a number of years ago now and I really should go and dig them out at some point, to see the state of preservation of the caudal vertebrae and identify which bones remain intact.  But, to return to the present line of inquiry, I rummaged around the metal box which held the small collection of animal bones I had collected over the years and found a match for the distal humeral fragment, that I had found at work, with the cleaned bones parsed from the remains of the shoulder of mutton meal.  And so, through the analysis of the morphological features present, combined with my previous handling experience of animal remains and the use of comparative modern examples, my hunch at the species identification had proved correct in this instance.  I felt a sense of satisfaction in my positive and appropriate analysis of this random fragment.

Oh I patted that dog (Canis familiaris) in the car park on the head by the way, watched its chocolate coloured eyes lock briefly and keenly with my own before it decided to wander back over to its owner on the other side of the small car park, perhaps knowing I had no treats to give it that day.  Next time I return to the nature park I hope I shall see it again, and perhaps then will be able to give it a treat in return.

Sometimes it is the little things in life that make you realize that we do not share this world just with one another but with a wide variety of life forms, each within their own lives.

Updated: Human Osteology Postgraduate Courses in the United Kingdom

14 Aug

Note: I originally wrote this post a few years ago in order to outline the available human osteology/bioarchaeology postgraduate courses in the United Kingdom as a guideline for the degree fees and topic availability.  However since then a number of substantial national and international changes have occurred.  These include, but are not limited to, the increase of undergraduate tuition fees to £9000.00 per academic year; the general increase of the price of Masters degrees; the new availability of student loans for Masters students; changes to Disabled Students Allowance from the 16/17 academic year onward; the transfer of some Student Finance grants to loans; the Government White paper released in May 2016 outlining challenges and changes needed in higher education, etc.

One of the more important changes was the outcome of the referendum in the United Kingdom whether it to remain or not a part of the European Union, this resulted in a very tight result in which the majority voted to leave the European Union.  This process will take many years, but the Government of the United Kingdom recently stated that it would guarantee European Union funding for projects signed before the Autumn Statement until 2020.  Doug, of Doug’s Archaeology, has an interesting and somewhat depressing post on what Brexit could mean for archaeology as a sector more generally

—————————————————————————————————————————————-

Whilst I was doing some light research for another article I made a quick list of every course in the United Kingdom that offers human osteology as a taught masters (either as an MA, Masters of Arts, or as an MSc, Masters of Science) or offer a distinctive human osteology module or component within a taught masters degree.  Human osteology is the study of human skeletal material from archaeological sites.  Human osteologists study bones to identify age, biological sex, pathology and pre- and post-mortem trauma alongside other avenues of research in human behaviour and activity, such as investigating diet and mobility of post populations.  The subject is generally only taught as a Masters level within the United Kingdom.

Within the list England as a whole is well represented within the universities highlighted, Scotland only comes in with two entries whilst Wales and Northern Ireland, as far as I know, offer no distinctive osteological courses at the Masters level.  Further to this the reader should be aware that some universities, such as the University of Leicester, offer commercial or research centers for human and animal osteology yet run no postgraduate courses that provide the training in the methods of osteoarchaeology.  Thus they are excluded from this list.

This information is correct as of September 2016, but please expect at least some of the information to change, especially in relation to course fees for United kingdom, European Union, and international students.  It should be noted here that the education system in the United Kingdom is internationally well-regarded and the educational institutions are often in the top 10% in world league tables; however it can be very expensive to study here, especially so in the consideration of prospective international students.  Please also take note of the cost of renting (especially in London and the south of the country generally) and the high cost of daily living compared to some countries.  The list is not an exhaustive attempt and I am happy to add any further information or to correct any entries.

Other Sources & Prospective Student Advice

As well as the list below, the British Association for Biological Anthropology and Osteoarchaeology also have links to human osteology and bioarchaeology courses in the United Kingdom.  You check the list out here.  The British Archaeological Jobs and Resources (BAJR) site, ran by David Connolly, also has a plethora of useful resources to check as well as an active Facebook group which is a great place to ask for advice.  I’ve also wrote a second post to compliment this one which entails what you, the prospective student, should keep in mind when looking at degree courses to pursue. You can check out that post by clicking the title here: Questions to remember when considering a postgraduate course in human osteology.

A Few Pieces of Advice

A piece of advice that I would give to prospective students is that I would strongly advise researching your degree by visiting the universities own webpages, finding out about the course specifics and the module content.  If possible I’d also visit the department and tour the facilities available and seek advice from the course leader with regards to potential research interests.  I would also always advise to try to contact a past student and to gain their views on the course they have attended previously.  They will often offer frank advice and information, something that can be hard to find on a university webpage or from a course leader.  Also please do be aware of the high cost of the United Kingdom tertiary education as prices have been raised considerably in the past few years and are likely to rise again, especially so in comparison to cheaper courses on the European continent.

Finally, if you know of any other human osteology or bioarchaeology Masters or short courses in the United Kingdom please do comment below or send me an email and I will add it to the list here.

Brief Updates: A Possible Publishing Rule of Thumb, Socio-Sexual Lives in Bioarchaeology & Memories of Fractures

8 Aug

I’ve been thinking a bit recently about the power of the written word, and of the associations with both personal jottings and more wider ranging long form pieces such as academic text books or investigative journalism.  Partly this has been guided by the growing number of books on my bedside, but also by a personal milestone in the publication of a bioarchaeology chapter by yours truly.  I’ll try not to mention this too much but it has been, and it will be, the realisation of a dream of mine to become a published author and particularly so in a topic that is close to my professional and personal interests.  But more on that below.

blogggggggggggggggg

Two of the texts discussed in this entry below are Ann Oakley’s part memoir and part sociology study in Fracture: Adventures of a Broken Body and Pamela Geller’s research into socio-sexual lives in the archaeological record, which investigates past human sexuality.

Publishing: The Invisible Researchers

The term Publish or perish is a popular and well-known academic phrase that highlights the fact that research that isn’t published appropriately, or in a relatively timely manner, can easily become lost to the archives and the relevancy of the researcher to their discipline to disappear.  Any academic employed at an educational institute and conducting research will likely regularly produce articles, chapters, and books as appropriate, and actively take part in conferences giving papers or leading workshops to disseminate and communicate knowledge.  This is a normal part of the workload (heavy though that can be) of a research position.

Whether that phrase is helpful or stressful depends on the context – rushed research can lead to false or doctored evidence and the increased pressure to publish, along with the normal duties of lecturing, likely being a course or module tutor, and the administration accompanying such positions, can indeed lead to a hefty work load.  My interest in this though is the invisible researchers who are not employed within academia but are located on the fringes, those such as myself who work full-time in other sectors and publish and research in our own free time.  This blog is a prime example of that, but also of the mixing of the boundaries between the personal and the academic which would not normally be found within journals or published volumes.  Rather this is space to inform, educate, and communicate the interests and experiences of the individual.  The published work, of which I have only a few examples currently with more emphasis currently on specialist reports, requires a change of tone and, often, of approach.

Publishing Date Rule of Thumb?

I’ve also recognised a relatively reliable rule of thumb for academic book publishing.  For instance, I’ve been eagerly awaiting the publication of my own chapter within an edited volume titled New Developments in the Bioarchaeology of Care: Further Case Studies and Theory, to be published as a part of Springer’s Bioarchaeology and Social Theory series.  The edited volume builds upon Lorna Tilley’s 2015 Theory and Practice in the Bioarchaeology of Care publication in identifying and interpreting cases of care provision in prehistory through osteological and contextual analysis, and by furthering the theoretical framework.  It is exciting to a part of such a volume as a result of the SAA session in 2015 and I’m keen to hold a copy of the finished work and to read the other authors contributions.  I’m also intrigued by the reception that the volume will hopefully receive and the criticism too, with the opportunity to learn from others in the field of bioarchaeology.

But the rule of thumb!  Springer obviously mentions their forthcoming volumes on their site as do other commercial online retailers, however I’ve noticed they tend not to add a specific date for publication whereas some retailers, such as Amazon, do under the title release date (1).  This is useful to know as the publishing date tends to change depending on when the individual chapter and volume editing and proof-reading tasks have been completed, and as to when the publishing production units can start to print.  In my case I’ve noticed the dates shift around a few times due to various factors but I’ve always known when roughly publication and release date should be, sometimes ahead of emails from the volume editors.  Of course this won’t really be a rule of thumb until the volume is published and collaborates my theory, but you can expect another blog post then!  If you have noticed the same trend please let me know below.

Socio-Sexual Lives In Bioarchaeology

Through serendipity I happened to come across Pamela Geller’s 2016 book The Bioarchaeology of Socio-Sexual Lives: Queering Common Sense About Sex, Gender, and Sexuality, published in the same Bioarchaeology and Social Theory series by the above and due for release shortly.  I am very tempted to order a copy of this volume as it seems to challenge the binary orthodoxy of sexuality and identity so prevalent within bioarchaeological analysis of past individuals and populations.  That is an interrogation of the assumption of stability with regards to the values of hetero-normative relations within today’s Western world that is so often projected onto past populations and cultures.

The wide range of cultural case studies and the deep chronological scope of the volume also promises to make it be an invigorating and exciting read.  As with the Bioarchaeology of Care publication, this volume probes the archaeological record into areas of research that have rarely been investigated in-depth, thus potentially opening up the record to a far greater scrutiny of the lived experience of sexual identity and gender.  As such, it is very much on my bioarchaeological books to read next list (you know, after I’ve read this other pile of books by my bedside table!).  It isn’t very often that I purchase bioarchaeology volumes as they can be quite expensive if they are not available in paperback or second-hand (2), but I’ll think I’ll make a change for this volume.  If I do I’ll be sure to write-up an entry for the blog.

Memories of Fractures

And so to bring this post to a timely conclusion I return to my opening paragraph.  One of my favourite books that I’ve had the pleasure of reading within the past few years remains the sociologist Ann Oakley’s (2007) Fracture: Adventures of a Broken Body, an essay on the impact of the author’s traumatically fractured humerus that covers much ground within a relatively slim volume.  I largely adore this book because it is so relatable and so readable, the descriptions of the personal and professional impact of her fracture is something that I can very much sympathize and empathize with.  However the strength is also the breadth of the book, through the historical, medical and sociological musings on the frailty, health and image of the human body and entwined identity.  This volume then represents a fine mix of the personal and the academic, never afraid to speak freely on the issues and challenges that face society in accepting the differences in human form and the obstacles.

The Great Questions of Bioarchaeological Research

To me then bioarchaeology and its associated disciplines offers the chance to investigate on a fundamental level one of the central facets of our existence; what does it mean to be human? How is this represented and approached in the archaeological record?  How were individuals treated within their respective populations, and what were the lived experiences of these populations and individuals like?  The ability to answer some of these questions, in part at least, endlessly fascinates me.  Some of the publications named above aim to answer these questions and may do just that.

Notes

(1).  I have just rechecked this and sadly my thumb of thumb can seemingly be thrown out of the window.  It appears that Amazon does seem to have a better rough date for volumes in preparation, but that by the final month or so within publishing and release date Springer also update their website.

(2).  Joining local or university libraries, where possible, can be great to order books in or to borrow books that are otherwise un-affordable or rare to find.  I generally only purchase bioarchaeology manuals that can be used in osteological analysis or are otherwise handy reference books, but otherwise some books can make great presents!

Skeletal Series Part 12: Human Teeth

28 Oct
teeeeeethhh

Basic human permanent dentition. Click to enlarge.  Image credit: modified from here.

Teeth, as a part of the dentition, are a wonder of the natural world and come in a variety of forms and designs in vertebrate animals, with perhaps some of the most impressive examples include the tusks of elephants and walruses.  They are also the only part of the human skeletal system that can be observed naturally and the only part that interact directly with their environment via mastication (White & Folkens 2005: 127).

Although primarily used to break down foodstuffs during mastication, teeth can also be used as tools for a variety of extramasticatory functions such as the processing of animal skins and cord production (Larsen 1997: 262).  As the hardest of the biological material found in the body teeth survive particularly well in both the archaeological and fossil records, often surviving where bones do not.  Teeth are a goldmine of information for the human osteologist and forensic anthropologist alike as they can be indicative of the sex, age, diet and geographic origin of the individual that they belong to (Koff 2004, Larsen 1997, Lewis 2009, White & Folkens 2005).

This entry will introduce the basic anatomy of the human dental arcade, deciduous and permanent dentition and the various tooth classes, alongside a quick discussion of the action of mastication itself.  But first, as always in this series, we’ll take a look at how teeth can be found during the excavation of archaeological sites.  This post marks the final Skeletal Series post to deal explicitly with individual elements of the human skeletal system.  The next few posts in the Skeletal Series will be aimed at detailing the methods used in aging and sexing elements in the adult and non-adult skeleton (and the success rates of the various methods), followed by posts introducing the pathological conditions that can be present on human skeletal remains.

Excavation

The 32 permanent human teeth, located in the upper arcade (maxilla) and lower arcade (mandible) of the jaws, each holding 16 teeth, are resilient to chemical and physical degradation.  Furthermore tooth crown morphology (the surface that consists of enamel) can only be changed by attrition (tooth wear), breakage, or demineralization once the crown of a tooth has erupted through the gum line (White & Folkens 2005: 127).  As such teeth are often found at locations where human remains are suspected to be buried or otherwise excavated.  Care must be taken around the fragile bones of the spanchnocranium (i.e. the facial area of the skull), defined as necessary, and, if needed due to fragility, the area may have to be lifted with natural material still adhered to the bone to be more carefully micro-excavated in the lab (Brothwell 1981: 3).

Circled in red, the teeth are located in the upper (maxilla) and lower (mandible) jaws. This individual, dating to the medieval period in eastern Germany, highlights a common occurrence in supine burials where the mandible often ‘falls’ forward as the muscles, ligaments and tendons decompose. Always be careful when excavating suspected burial features as both bone and tooth can be chipped by trowels or other metallic excavation implements. Photograph taken by author.

Loose dentition may be found around the skull itself as teeth can be loosened naturally postmortem as natural ligaments decompose.  Sieving around the location of the skull may prove useful in finding loose teeth and also the smaller bones of the skulls (such as the ear ossicles).  In the excavation of non-adult remains, or of suspected females with fetal remains in-situ, great care should be taken in recording and the excavating of the skull, torso and pelvis.  As mentioned below teeth form from the crown down, as such deciduous or permanent teeth during growth may be loose in exposed crypts in the mandible or maxilla (Brickley & McKinley 2004).  Furthermore due to the small size and colour of the 20 deciduous teeth, especially the crowns during the formation and growth of the teeth, may be mistaken for pieces of dirt or rocks.

Tooth Anatomy & Terminology

The basic anatomy of teeth can be found in the diagram below, but it is worth listing the anatomical features of a typical tooth here.  The chewing surface of the tooth is called the occlusal surface and it is here that the crown of the tooth can be found.  The crown of a tooth is made of enamel, an extremely hard and brittle mixture of minerals (around 95-96% hydroxyapatite).  The enamel is formed in the gum and once fully formed contains little organic material.  The demineralization of teeth can repair initial damage, however this is limited in nature.  Dentin (sometimes termed dentine) is the tissue that forms the core of the tooth itself.  It is supported by a vascular system in the pulp of the tooth.  Dentin can only repair itself on the inner surface (the walls of the pulp cavity), but dentin is a softer material than enamel and once exposed by occlusal wear it erodes faster than enamel.  The pulp chamber, in the centre of the diagram below, is the largest part of the pulp cavity at the crown end of the tooth.  The pulp itself is the soft tissue inside the pulp chamber, which includes the usual trio bundle of vein, artery and nerves (V.A.N.).  The root of the tooth is the part that anchors it into the dental alveolus tissue (sockets) of the jaw (either the maxilla or mandible).

Toothanatomy2

Cementum is the bone type tissue that covers the external surface of the roots of teeth.  The apex, or apical foramen, is the opening at the end of each root, which allows for the nerve fibers and vessels up the root canal into the pulp chamber.  Heading back up to the occlusal surface of the tooth we encounter cusps of the crown, each of which have different individual names depending on their position.  Upper teeth end with the prefix -cone whereas lower teeth end with the prefix -conid (see details here).  Finally we have fissures, which are clefts between the occlusal surfaces between cusps.  Fissures help divide the cusps into patterns and are helpful to know to help identity individual teeth (specifically the molars).  Above information taken from White & Folkens (2005: 130-131).

As previously highlighted there are some directional terms that are specific to the dentition, but it is pertinent to repeat some of the key aspects here for clarification as tooth orientation is important –

Apical: towards the root.
Buccal: towards the cheek (the buccinator muscle- the terminator of the muscle world!), used in realtion to posterior teeth (premolars and molars) only.
Cervical: towards the base of the crown or neck of the tooth (often called the cementoenamel junction).
Distal (direction): away from the midline of the mouth, opposite of mesial.
Incisal: towards the cutting edge of the anterior teeth.
Interproximal: between adjacent teeth, also useful to know and be able to identify are interproximal contact facets (IPCFs) which can indicate anatomical location of  tooth.
Labial: surface towards the lips, anterior teeth (canines and incisors) only.
Lingual: of the tooth crown towards the tongue.
Mesial (direction): towards the midline, closest to the point where the central incisors contact each other.
Occlusal: towards the chewing surface (crown) of the tooth.

teethdirect

Tooth anatomical direction terminology and legend of tooth position, above is the maxillary dental arcade. Typically the uppercase and lowercase numbers refer to maxilla and mandible positions respectively, and often include a L or R for left or right hand side for quadrant location. In deciduous dentition lower case letters are used, in permanent dentition capitalization is used. Premolars are often 3rd (1st premolar) and 4th (2nd premolar) after palaeontological standards.

Above information taken from White & Folkens (2005: 128) and here.

A different method for recording the presence/absence and state of the individual teeth from archaeological skeletal populations is proposed by the British Association of Biological Anthropology and Osteoarchaeology (BABAO) as mentioned above.  In this method, proposed by Connell (2004: 8) the deciduous and permanent dentition are given a separate letter or number:

It should be noted that if compiling a large inventory for a population it is best to individually number and identify each tooth after the Buikstra & Ubelaker 1994 standards (but see also Bone Broke).

Deciduous & Permanent Teeth

Humans have only two sets of teeth during their lifetimes.  The first set, known as the deciduous (primary or milk) teeth, are the first to form, erupt and function during the early years of life (White & Folkens 2005: 128).  The primary dentition consists of central incisor, lateral incisor, canine, first molar and second molar in each jaw quadrant, making a total of 20 individual deciduous teeth in all.

These are systematically lost and replaced by the permanent, or secondary, dentition throughout childhood, adolescence and early adulthood.  As noted above these include a central incisor, lateral incisor, canine, two premolars, and three molars in each jaw quadrant making a total of 32 individual permanent teeth in all.

The sequencing of the pattern of tooth eruption plays a vital clue in estimating the age of the individual, whilst tooth attrition (wear) is used in estimating individual age after the permanent dentition have fully erupted (White & Folkens 2005: 346).  The loss of a tooth, or teeth, antemortem (before death) can lead to alveolar resorption over the empty tooth socket.  Individuals who have no teeth left (often elderly individuals or individuals suffering periodontal disease) are termed edentulous.  This can lead to problems pronouncing words, the cheeks sagging inwards and problems chewing or grinding food (Mays 1999).  Perhaps the most famous example of this is one of the Dmanisi hominin fossils (crania D3444 and associated mandible D3900) whose crania lacked any teeth whatsoever and showed alveolar bone resorption of both the mandibular and maxillary arches.  However, if this is evidence of conspecific care, or just of survival, is not known (Hawks 2005).

Deciduous tooth formation begins only 14-16 weeks after conception.  White & Folkens (2005: 364) note that there are four distinct periods of emergence of the human dentition: 1) most deciduous teeth emerge and erupt during the 2nd/3rd year of life, 2) the two permanent incisors and first permanent molar usually emerge around 6-8 years old, 3) most permanent canines, premolars, and second molars emerges between 10-12 years old and finally 4) the 3rd molar emerges around 17/18 years old – although this can vary.  Note also that there are some differences between the sexes and between populations (Larsen 1997, Lewis 2009, Mays 1999).  Trauma, pathological conditions and diseases can also influence tooth development and eruption rates, often delaying the eruption of the permanent dentition and sometimes leaving visible deformities in the teeth themselves, such as linear enamel hypoplasia (sign of stress) or mulberry molars (specific sign of disease) (Lewis 2009: 41).

Tooth Class

Teeth in humans are classed into 4 separate classes of tooth based on function and position.  The classes include incisors, canines, premolars and molars, each aiding the other during the mastication of food.

teeth jawline

The human permanent dentition. Notice the larger size of the maxilla (upper) crowns compared to the mandible (lower) crowns and the differences between the roots of the same class of tooth. The first molar is the largest of the molar and the first to erupt. This can tooth can often have evidence of attrition on its cusps and crown when the 2nd and 3rd molars lack abrasion due to the 1st’s early eruption. Not to scale. Image credit: Biologycs 2012.

Maxilla Teeth:

Incisors (general: crowns flat and blade-like, outline of dentine occlusal patch is often rectangular or square if exposed by wear)

The upper incisor crowns are broad (or mesiodistally elongated) relative to their height, and have more lingual relief.  The central incisor crown is larger and more symmetrical than the lateral incisor crown but the roots are shorter and stouter to crown size than to the lateral incisor roots (White & Folkens 2005: 142).

Canines (general: crowns are conical and tusklike, canine roots longer than other roots in the same dentition, can be confused for incisors)

Upper canines are broad relative to their height and have more lingual relief, with apical occlusal wear that is largely lingual (towards the tongue) (White & Folkens 2005: 139).

Premolars (general: crowns are round, shorter than canine crowns and smaller than molar crowns, generally only have two cusps, usually single rooted but can be confused for canines but note shorter crown height)

The upper premolar crowns have cusps of nearly equal size and the crowns are more oval in occlusal outline.  Further to this the crowns of upper premolars also have strong occlusal grooves that orient mesiodistally between the major cusps, this is a key identifier for maxilla premolars (White & Folkens 2005: 140).

Molars (general: crowns larger, squarer, bear more cusps than any other tooth class, have multiple roots, 3rd molars sometimes mistaken for premolars)

Generally peaking the maxilla molars go from largest to smallest (1st molar to 3rd molar) in size and morphology.  The crowns generally have 4 cusps.  The 1st molar has three roots (two buccal and one lingual, which when seen from the buccal position the lingual root comes into view in the middle of the two buccal roots).  The occlusal surface is described as a rhomboid in shape with 4 distinctive cusps.  The 2nd molar has three roots but the two buccal roots are nearly parallel with each other, and is described as heart shape in the occlusal view.  The 3rd molar has three roots present but the two buccal roots are often fused, and the outline of the occlusal surface is also described as a heart shape.  The 3rd molar also shows greater developmental variation than either the 1st or 3rd molars, and are often the tooth that is congenitally missing.  All roots of the molars angle distally with respect to the major crown axes (White & Folkens 2005: 152).

Mandibular Teeth:

Incisors

Lower incisor crowns are narrow compared to their height and have comparatively little lingual topography, further to this the roots are usually more mesiodistally compressed in cross-section (White & Folkens 2005: 139).  The lower central incisor crowns are slightly smaller than the lower lateral crowns, with shorter roots relative to the crown and absolutely than lateral incisors (White & Folkens 2005: 142).

Canines

Lower canines have comparatively little lingual relief compared to the upper canines, and the apical occlusal wear is mostly labial.  The lower canines are also narrow relative to their height (White & Folkens 2005: 139).

Premolars

Lower premolar crowns are more circular in occlusal outline than upper premolars, and have comparatively weak median line grooves.  In lower premolars the long axes of the roots are angled distally relative to the vertical axis of the crown.  When IPCFs are present they are mesial and distal in location (White & Folkens 2005: 150).

Molars

Generally speaking the mandibular molars go from largest (1st molar) to smallest (3rd molar) in size and morphology, same as the maxilla molars.  The 1st mandibular molar is very recognizable as it has the largest crown with 5 cusps in the distinctive Y-5 cusp pattern and a pentagonal occlusal surface.  The two roots of the tooth tend to be long, separate and divergent.  The 3rd molar is smaller than the 1st or 2nd and have more irregular cusps and lack distal IPCFs, it also has two short and poorly developed roots that curve distally.  The occlusal surface is often described as crenelated and ovoid in shape.  The 2nd molar crown is an intermediate of the 1st and 3rd crowns (with 4 cusps) and roots (which have a distal inclination) in morphological terms, but has a distinctive +4 pattern of the occlusal surface.  All roots of the molars angle distally with respect to the major crown axes.

For tooth identification there are four questions to bear in mind:

A) To which category (or class) does the tooth belong?
B) Is the tooth permanent or deciduous?
C) Is the tooth an upper or a lower?
D) Where in the arch is the tooth located?

Although I’ve hinted at some of the answers above, those questions are a whole other post!  But do investigate the Human Bone Manual by White and Folkens (2005) for further information and/or Brothwell (1981) and Mays (1999).

This post will be updated to include the muscles of mastication.

Bone Quiz: Revisiting Germany

14 Oct

Unfortunately I’m only visiting Germany in this blog entry and not personally!  Germany has recently been in both the education news and the osteo news though, so I’m always happy for a tenuous link to one of my favourite countries.

Free Education!

There has been a recent announcement that each of the 16 autonomous states in federal Germany have now abolished their tuition fees at their public universities, with both German and international students being allowed to take academic courses tuition fee free from 14/15 (as long as they are completed within a reasonable timescale).  Each state (Länder government) in Germany is responsible for its own education, higher education and cultural affairs, and higher education is a public system funded with public money.  This is a major step for Germany, although the decision can of course be overturned in the future as states weigh up various options ad political climates change.  Recent economic news has shown that whilst the UK and USA economies are growing (slightly), the Eurozone as a whole is still stagnating and economically contracting – still, Germany is certainly doing better than some of its economic partners in Europe.

Past Populations

Meanwhile, over at the University of West Florida Kristina Killgrove (of Powered by Osteons fame) and graduate research assistant Mariana Zechini have started a new project blog aimed at investigating and digitally documenting archaeological artefacts and biological remains.  One of their first projects was the 3D scanning and modelling of the teeth of individuals from the medieval population of the city of Cölln, in eastern Germany (see here).  Cölln was the sister city to Berlin, each probably founded around the 13th century on opposite sides of the river Spree, which today snakes through modern-day Berlin which now engulfs both sides of the river.

Taking place at the Virtebra lab (Virtual Bones and Artefacts lab) at the university, the aims are to digitally preserve and produce 3D models of the teeth to help kick-start a teaching collection.  The remains, from archaeological deposits identified as the city of Cölln, were recovered from the German excavations of a large medieval cemetery that took place at Petriplatz, Berlin, from 2007-2010, which uncovered the remains of 3718 individuals.  Back in 2013 Dr Killgrove also took the teeth to be tested for strontium isotopes (geographic) at UNC Chapel Hill (read more here) and the latest Virtebra blog post discusses the results of some of these tests (here).  I don’t want to spoil the results, so check out the blog entry and read up on the interesting archaeology of Cölln and Berlin!  The teeth that have been scanned are available and accessible as models at the GitHub site here.

Bones, Bones, Bones…

So this German (osteo and education) news reminded me of the 6 happy weeks I spent in the wonderful city of Magdeburg, on the EU-funded Grampus Heritage organised Leonardo Da Vinci scheme back in 2011.  I worked with a bunch of awesome UK students with a wonderful German team and, rarely for archaeology, it was a fully funded project.  It was on this archaeology trip that I got to excavate human remains in a medieval cemetery, which was a real honour.  But I wonder if anybody who reads this blog wants to test their own osteo skills and identify the bone and its osteological landmarks below….

1. a) Identify the largest skeletal element inside the yellow rectangle.

—-b) Adult/non- adult, and why?  Side the bone.

2. a)  Identify the structures in the red circle.

—-b) Name 2-3 muscles that have tendons that insert on either of the structures.

I’ll put the answer up in a week or so – in the meantime please feel free to comment away.

LBK Almost Got Away

I almost forgot to mention that I’ve also conducted previous archaeological research into mobility of the Neolithic Linearbandkeramik (LBK) culture for my MSc dissertation back in 2012.  The focus was on the statistical testing of the results of a literature review of strontium isotope results from 422 individuals across 9 LBK sites in Central Europe, with the main cluster of sites located in southern Germany.  You can read my research here!
