Stuck at my Desk With a Packet of Jaffa Cakes

As has already been posted today, the osteo team from Cardiff University are currently out in Turkey, on site at Catalhoyuk and apparently for their day off are lounging by the pool, a particularly difficult task I imagine. As well as the bone-iologists, one colleague is in Iceland working on a site out there and another is currently excavating in Romania. Cardiff is seeming massively unappealing and rather dull at this point in time. Why a PhD in medieval and early post-medieval pottery from Wales seemed a good idea three years ago when I applied for the studentship here is beyond me.

 

Despite my jealous grumblings (mostly to myself as the post-graduate room is so quiet and now to you) this has been an informative, busy and exciting couple of years. Having the ability to spend three years on a subject you love is a luxury and one I keep having to remind myself of in the dark writing up stage. Post-graduate life here in Cardiff has been amazing fun and it is strange to think that that will all have to end once finished. It is quite difficult to watch others around you completing and passing vivas, which ultimately leads to a change in dynamic within the community you live and work in, as well as rely on, to provide support through what can be incredibly challenging years.

 

The post-graduate room here at Cardiff is central to the developing research community and it is where many a thesis has been written and are in the process of being written now. Friendships, relationships and collaborative projects are developed in this room, many of which last beyond the PhD timescale.

 

One collaborative project which has been recognised as important to all who spend time in this room is the Jaffa Cake challenge. We have sampled and tested the full range of Jaffa Cakes available, including the time old favourite McVities as well as the other supermarket alternatives. I’m afraid I don’t have any official stats and as the room is empty have not been able to call for a show of hands today on the matter, but we believe as a collective to have come to a conclusion on the perfect Jaffa Cake: Lidl’s finest Sondey Orange Jaffa Cake. It has the perfect balance of chocolate, orange and soft cake base, none of this slightly crunchy, could actually be stale, quality you often find with the branded variety.

 

I couldn’t imagine doing anything but archaeology with regards to a career and even though the last 6 months have been a struggle, my archaeological spirits have not been dampened, for at least I always know that the post-graduate room (even on a quiet day like today) can provide solace, a friendly ear – when people aren’t on amazing field projects – and a packet of Jaffa Cakes.

Live dispatches from the Tooth Fairy

So, now you know. The Tooth Fairy is an archaeologist.

Archaeologists get everywhere. Like sand. This also applies to  jobs, so it’s not totally impossible that someone who specialises in the minute structures of teeth (see my previous post from DayofArch 2011) would end up in the overwhelmingly awesome Human Origins Research Group at the Natural History Museum, London.

Natural History Museum

For starters, this is an awesome place to work. Yesterday I found out that during WWII, the collections were evacuated to stately homes across the country to escape the Blitz… complete with associated researchers. And there’s a basement here that’s really a bomb shelter which was used by Churchill as a telephone exchange – part of the secret tunnels which run all under this area up to the Palace and War Rooms. Herman Hess apparently even spent a few nights in the Anthro Stores before his trial.

And today, on the Day of Archaeology, this particular Tooth Fairy is gearing up for more research than you can shake a stick at. In relation to the main project I work on at the NHM I’ve:

uwrapped my new camera toy;

eaten cake and discussed human origins/Euro2012; and

discovered a disturbing image mode setting on the new camera.

I’m also getting ready to go out to the field to look at the teeth of children who died in central Anatolia (Turkey) sometime between 10,500-8,500 years ago.  These are the remains of subadults from the amazing site of Aşıklı Höyük, the earliest settlement of the Anatolian Plateau.

I’ll be looking at the microscopic records of growth captured on every tooth–perikymata–to see how these children lived and grew. Like tree-rings, the lines on the outside of our teeth give a lot of information on how we grew (here‘s a more in-depth explanation). It’s a way to find out about health and development in early childhood at the very beginning of human settlement. Were there lots of growth disruptions? Can we see records of illness that might suggest seasonal diseases related to shifting subsistence patterns? That tell us about birth spacing?

I’m excited to find out. Even if I will totally get green dental impression material all over my nice new lab coat. It’s the price you pay for science!

Anyway, my days are pretty varied, but you can certainly keep up with me @brennawalks, or follow @ah_arkeoloji for more on Aşıklı Höyük.

And all the other bits!

As we work closely with archaeological planners and advisors, particularly the English Heritage Greater London Archaeological Advisors in London, the scope of all of our fieldwork and post-excavation strategies follow nationally agreed strategies, we have a really structured process that guides us through the excavation and analysis works. So my specialist osteological analysis and reporting will tie in to specific research questions generated for each site. On large projects like our post-medieval cemetery excavation in Bethnal Green, I will also engage with other specialists, particularly our small finds specialist, Helen MacQuarrie, who will be looking at the coins, dress accessories such as hair combs and buttons that we found with the burials, and our dendrochronologist Anne Crone, who

has been working to identifying the species that were used for the manufacture of wooden gravemarkers, which we also found at the site. Anne is also blogging about her day today – worth having a look. And I’ve uploaded a picture of one particularly interesting burial we found with a coin placed in each eye orbit as a symbolic payment for transport into the afterlife.

As an osteologist, I also look into the variation in funerary practices that were adopted in the past. The Bethnal Green burials were interred in wooden coffins, mostly covered with an outer textile that tends not to survive very well. The textile was held in place by upholstery pins and the coffin makers placed the pins in a range of patterns to add a bit of variation to the design of the coffin. Additional metal decorations were added, including angels and urns with flowers as well as sun-rays and rosettes. It’s interesting to see if the construction and decoration of the coffin varied, either between the sexes or by age or showed any variation across different sites.  So after recording each skeleton, I’ll catalogue the coffin size and decoration from site records and photographs and hopefully quantify the changes. You can see the variation in the coffin decorations in the site photo and this is generating a mass of data that will hopefully provide some really interesting results. Some of the burials had surviving coffin plates, which tell us the name and date of death of the individual. We can try and identify these individuals in the surviving parish records such as birth, marriage and death records, the census records, parish rate books and in wills, to try and broaden what we know about their lives. At the end of the analysis, we will bring together all of the research and evidence in a site-specific monograph, so the results will be fully accessible in the public domain together with the archived finds, which will be deposited at the LAARC.

Skeletons, but not in cupboards

Hampshire Arts & Museums Service is carrying out an audit of all the human remains in its Collections.  Where appropriate, this includes the rebagging and reboxing of material.  Garrard Cole, currently an Hon Research Assistant at UCL, is tackling four skeletons from Harrow Way Farm, Penton Mewsey, excavated by the Test Valley Archaeological Trust in 1988.  This improvement in the physical storage conditions goes hand in hand with an update of the associated records and  compilation of a database.

All the lovely skeletons!

Just finished recording a juvenile skeleton with lovely skeletal preservation, which meant a range of pathological changes were clear. The most obvious change was destruction of the bone at the base of the tooth root for the second deciduous molar in the mandible, with the bone destruction surrounded by a layer of porous new bone formation. The tooth crown had been destroyed by caries (cavity) and it seems likely that a secondary bacterial infection had developed into an abscess, which had drained into the surrounding gums. This is quite a severe change considering the pattern of tooth eruption suggests the child was only aged about 4-5 years when they died.

This particular child had also suffered from previous episodes of disease; their leg bones, particularly the femora (thigh bones), showed marked bending most likely indicating a vitamin D deficiency rickets. We need to form vitamin D either in our skin following exposure to the sun or from our diet, oily fish and eggs containing natural sources of vitamin D. A poor calcium intake in the diet may also be an important factor influencing the onset. It’s likely that a range of factors such as poor living and working conditions, limited diets and increased air pollution during the post-medieval period contributed to cases of rickets. There were also plaques of bone formation over the inside of the cranial bones, with prominent outgrowths forming in the occipital bone at the base of the skull. The deposits were thickened and formed of a long-standing remodelled bone layer, which suggests they had survived with the cranial inflammation or non-specific infection for quite some period.

Osteology at AOC Archaeology Group

I’m very lucky to have a job that I absolutely love doing. My role is to excavate and analyse the human remains that we find across our archaeological sites. It can be a diverse role – last week I looked at an Early Bronze Age adult cremation burial, next week I’ll be looking at some medieval burials found underneath a chapel floor. But today I’m studying one of my favourite groups – post-medieval burials fromLondon! The bone surface preservation is usually really good in post-medieval burials, which means we can see a great range of things on the skeleton, whether it’s a slight developmental anomaly or a more severe pathological change.

The skeletons I’m looking at are from a former burial ground dating from 1840 to 1855 from Bethnal Green. The ground was privately owned by a pawnbroker – he clearly saw an opportunity to make some money from the high mortality rates in the parish and surrounding area! We excavated the burial ground over six extremely muddy months last year, prior to the building of a new nursery school on the site. As you can see in the site photo, we’ll uncover and clean the coffins before recording and photographing them. We recovered just over 1000 burials; some of the graveshafts contained up to 54 burials and were up to 7.5m deep.

When back in the office, having cleaned the skeletons, I’ll start by laying out all of the remains and then producing an inventory of which bones are present or missing. Post-medieval burials w

ere often placed in vertical stacks in graveshafts, which sometimes collapse over time. So I’ll look for any possible mixing between the bones (if I have three skulls for one burial there’s a problem!) and I’ll check the site records, which will indicate if a coffin was damaged or had collapsed. I’ll then assess the bone preservation and estimate the age and sex of the individual as well as taking a host of measurements – for this site I’m particularly interested in seeing how well the juveniles were growing compared to other groups or compared to modern studies.

The best bit of the job, for me, is to determine how healthy individuals were in the past. I’m a true geek and I’m fascinated by how the skeleton can respond to disease processes and how, by recognising and recording those changes, we can help to reconstruct a bit more about what life was like in the past. I admire fieldwork archaeologists – how they can look at a hole in the ground and work out what activity had taken place on the site – but I love that my work has a more personal aspect by looking at the evidence from the people themselves. It’s a very emotive subject, but hopefully by trying to ascertain as much as about them as possible, as carefully as possible, we are gauging a respectful and fascinating insight into their past lives.

Right – ready for the first skeleton of the day. I’ll complete a paper-based record for each skeleton, which forms part of the site records that are archived with the relevant museum when the project is finished, in this case the London Archaeological Archive and Research Centre, so if anyone needs any further information they can directly access the records. We also have a specific osteology database for generating our report data, which can get big depending on how many pathologies there are on a skeleton or how long-winded I’m being. I’ll update the blog later on to show you what I’ve found. I can already see traces of a nice cranial infection on this individual!

Don Walker: Archaeological Help for Doctors

Caution: osteologists at work

The Digitised Diseases project, a collaboration between the University of Bradford, Museum of London Archaeology (MOLA) and the Royal College of Surgeons, is producing high resolution laser 3D scans of diseased human bones. These will be included in a medical resource website aimed at informing and teaching doctors and other professionals. The advantage of working with bone from archaeological sites and museum collections is that they can illustrate rare lesion types, some of which may not appear frequently in 21st century clinical medicine. Without access to antibiotics, sufferers of chronic diseases in the past could go on to develop the full extent of bony lesions. Having won JISC funding for the project, the team is currently selecting appropriate examples of pathological change for scanning. Following the excavation of a large number of burial grounds from different periods ofLondon’s history, MOLA is uniquely placed to provide interesting examples of disease for scanning. Each bone is entered into the database which produces an index number. They are then described, photographed and scanned. The photographs are then mapped onto the scans by gaming industry experts to produce the final textured 3D image. The illustrations below show scanned ‘blanks’ prior to photographic mapping.

About me
I am a professional archaeologist who lives and works in Ireland. Part of my professional work involves overseeing the archaeological programme of Bord na Móna, where I act as Project Archaeologist. Bord na Móna is the commercial Semi-state body with responsibility for the development of the Irish national peat resource. Bord na Móna owns and manages more than 80,000 ha of land spread across Ireland. Most of this is peatland which has preserved a wealth of organic archaeological and palaeoenvironmental material. I also act as Project Archaeologist for the Irish Concrete Federation where I am responsible for implementing the Archaeological Code of Practice which was agreed with government in 2002. But on this particular day I am spending my time working on my own archaeological research.

Writing and Parenting on My Day of Archaeology

Last year, I wrote a fairly general post about my life as a Roman bioarchaeologist for the Day of Archaeology – So You Want to Be a Roman Bioarchaeologist?  This year, I thought I’d write a more week-in-the-life kind of post.

For many archaeologists, the summer is prime digging season, a time to get a ton of research done and data collected.  My summer is a bit more complicated this year, though.  I am not in the field, but rather am furiously finishing up a few writing projects with end-of-summer deadlines, packing and planning to move 700 miles away for a new faculty position that starts in five weeks, and leaving the house at 2:30pm every weekday to head to summer camp, where I pick up a 3-year-old who is exhausted, sticky with sunblock, and reeking of bug spray.
