OM NOM NOM (Part Two) or Did I REALLY Use That Same Old Bad Joke To Introduce A Post on Butchery

Note: Today’s blog post will be the last one for a bit – due to my workload piling up for my PhD, I’ve decided to take a month long hiatus from blogging. Hopefully, having the entirety of February to catch up on my lab-work (and also celebrate my birthday on my downtime because I’m a February baby! Please send all birthday coffees here thank you) will get me ahead of schedule and I can get back to weekly blog posts come March. Thanks again for all of your support and hopefully I’ll see some of you when I get back – until then, remember you can also follow me on Twitter where I’m sure I’ll occasionally pop in to complain about animal bones!

Okay…I know I said that I wouldn’t use that extremely bad, extremely old joke to introduce a blog post…but this one is basically a companion piece to the previous OM NOM NOM post on gnawing, so it doesn’t count…I think.

Well, I promise I won’t use it again after this, okay? Okay.

Anyway, let’s talk about butchery.

07a74d2f-62fb-4f33-9cab-6916b07a8f7c
Various animal bones that show evidence of butchery.

“Butchery” is basically what zooarchaeologists call any physical characteristics that may indicate that the bone has been modified by humans. There can be many reasons why bones will be modified, but most commonly its for consumption. Here’s a brief overview of three common butchery marks that can be found on faunal bone in the archaeological record:

Cuts

Cut marks look like thin striations in the surface of the bone. They are mostly associated with activities like skinning/de-fleshing. Based on other characteristics, zooarchaeologists can determine whether a cut mark was made by a stone blade or a metal blade. Stone blades create shallow v-shaped marks with parallel striations (Potts and Shipman 1981), while metal blades will made deeper, slightly angled v-shaped marks (Greenfield 1999).

Chops

Slightly different from cut marks are chop marks – these are marks that were made by blades that hit the bone at a perpendicular angle, causing a V-shape that’s much broader than a cut mark (Potts and Shipman 1981).

Marrow Cracking

One very specific form of butchery that’s pretty easy to identify is marrow cracking or marrow extraction. Marrow is a valuable product that can be extracted from various bones simply by breaking into the shaft. We can recognise bones that have been cracked or butchered for marrow by the fractures and splintered fragments left behind (Outram 2001). Depending on the tool used to break the bone, “percussion notches” can also be found along the fractures.

Obviously there’s much more when it comes to butchery marks, but these three are arguably some of the common forms of butchery that you run into as a zooarchaeologist. To be honest, there’s something really wonderful about finding bits of butchery when you’re excavating – running your fingers along the striations in the bone, it’s amazing to think that hundreds, thousands of years ago, someone created these marks…probably with a stomach as hungry as mine, too.

I’m gonna be honest, I get so hungry when I work with animal bones sometimes…is that weird? It’s weird, right. Hm.

“Death Positivity” for Pets: Are We Changing Our Attitudes Towards the Death Of Animals?

Content Warning – Today’s blog post will talk at length about animal death and will have some photos of taxidermy animals. Please proceed with caution and feel free to skip the blog post entirely if this is too upsetting.

Caitlyn Doughty, founder of the Order of the Good Death, gives a talk at a Death Salon event in Seattle (Photo Credit: @DeathSalon on Instagram)
The “Death Positivity” movement has truly become part of the mainstream discourse recently, ranging from a general increase in appreciation for all things aesthetically macabre, to more organized events that educate others on death and the culture surrounding it. Arguably at the forefront of this movement in the United States is Caitlyn Doughty, a mortician who started the Order of the Good Death as a means of engaging with death and dying in a more positive manner and combatting the anxieties that surround death in modern society (Troop 2013). Doughty eventually began working with other organizers to create “death salons” – based on 18th century intellectual salons, these events gather academics, professionals, and creatives (such as musicians, artists, performers, and even chefs!) together to discuss aspects of death and the culture around death (Rosenbloom 2013).

But while our attitudes towards human death may be changing, what about our attitudes towards animal death? This may be a more complicated question than I originally thought – after all, given our utilisation of animals as subsistence, product manufacturers, and sometimes companions, humans will find themselves constantly confronting animal death. However, there are two specific examples of recent trends that I’ve noticed as someone who consistently works with animal remains in their everyday life…

Perhaps one example of changes towards animal death is the popularisation of “vulture culture” online – this term often refers to enthusiasts for collecting animal remains, either as skeletal elements or as taxidermies. Not everyone in the community processes their own remains, but everyone expresses a passion for collecting specimens via online sellers or by finding naturally defleshed remains in the wild. Some enthusiasts are also artists that incorporate animal remains into their artwork somehow.  It is usually emphasised that “vulture culture” collections are derived from naturally deceased animals as part of their ethics (Miller 2017).

Another example of “animal death positivity” could also be seen in the rise of pet mortuary businesses that specialise in “alternative aftercare”. This can either be as a full taxidermy piece, as a partial piece (for example, preserved tails or paws), or in skeletal form. Precious Creature Taxidermy, an alternative aftercare and taxidermy business run by Lauren Lysak in California, offers various aftercare services in lieu of what we may consider “traditional human funerary services” that includes the previously mentioned processes as well as cremation (Lysak 2018). Although it may seem a bit macabre to taxidermy one’s pet, you could also consider this as a deeper acceptance of death and its constant presence around all of us…in taxidermy form.

So, are we entering a new phase of “death positivity” with regards to animals? Do we even have a right to feeling “death positive” towards non-human species – after all, of course, many animal deaths are directly caused by human activities. I think that, ultimately, this is a very complicated topic that has many layers to it regarding concepts of posthumanism, of ethics, of agency, and so on – perhaps this requires another, more lengthy blog post! However, at least with regards to how humans experience the death of animals, specifically pets, I think we are making strides to better understanding the processes of death and utilising some aspects of “death positivity” as we apply it to humans in our overall understanding of the concept as a whole.

Bones that Look like Other Bones: A Mini Post about Foxes and Badgers

It’s been a while since I’ve made a Comparative Anatomy post! But after running into an issue with a possible fox/badger bone fragment, I figured it might be time to make a new one. And if you have any particular comparative anatomy posts that you’d like me to make in the future, please feel free to contact me about it!

Badgers and foxes – two animals that I have literally never seen in the wild until I moved to England. Honestly, I don’t even think I ever really though about either of them until I moved here. And yet, both are relatively common around Britain, which has caused me to become quickly familiar with their bones on the off-chance that they get mixed into an assemblage I’m currently working on (one of the many problems you face as a zooarchaeologist who works in a regional area that is so different from the one you grew up in!). There’s way more detailed comparative guides out there (see “References” below), but here’s a quick little post showing off some of their anatomical similarities and differences:

Skulls

img_3408
On the top is the skull of a badger. On the bottom is the skull of a fox.

At first glance, fox and badger skulls may look very much alike! However, there are some significant differences that will make telling the two apart a lot easier than you’d think. Possibly the biggest difference is in the general characteristics of each skull – badger skulls tend to be a bit “chunkier” and more robust, yet also shorter with a less elongated “snout” area, so to speak. Foxes, on the other hand, are more flat, with more elongated, perhaps even graceful arches and curves and are a bit thinner in comparison.

img_3413
On the right is the back of a fox skull, and on the left is the back of a badger skull. Note the difference in sagittal crests!

Another key difference can be seen if we look near the back of the skull where theses long ridges (called sagittal crests) can be found. Both foxes and badgers have relatively prominent sagittal crests, but badgers’ crests are a bit bigger for the most part.

Teeth

img_3417
The lower right mandible and teeth of a badger.

Badger and fox teeth look relatively similar as well. They have a sort of curvy, “wave”-shape that you can also see in dogs (see my Teeth post for more information). However, there are slight differences. Badger teeth, as you can see above, are arguably flatter, especially in the back molars.

img_3419
The lower mandible (and teeth) of a fox.

Fox teeth, on the other hand, are much more sharper and tend to be in greater number than badgers.

Long Bones

img_3421
From left to right: badger humerus, badger femur, fox femur, and fox humerus.

There are better and more detailed guides out there that get into all of the long bones of both badgers and foxes (see “References” again), but for the sake of brevity we’ll just be looking at two: the humerus and the femur. Again, you could argue that a general rule of thumb is that fox bones, unlike badger bones, are a bit thinner and longer. Badger bones are more robust, but shorter.

The humerus in a badger is very characteristic of this, as it is very short, yet robust. The hole at the bottom of the humerus is very oval shaped. In foxes, on the other hand, the humerus is much more elongated and thin. They also have a hole at the bottom of the bone, but this one is arguably more circular than ovular.

As for the femur, possibly the best indicator for what species you’re working with can be found at the “neck” at the top that leads to the little round bump known as the “femoral head”. Foxes don’t really have much of a “neck”, so the femoral head basically sits on top after a bit of a dip. As for badgers, their “neck” is much longer and more visible – the top of the bone clearly thins out into this “neck” as it leads to the femoral head.

Phalanges

img_3423
On the right are two fox phalanges, and on the left are two badger phalanges.

Honestly, if you’re tasked with differentiating between the phalanges of a fox and badger…yeah, uh…good luck! Again, you could roughly estimate based on general size, as foxes generally tend to be larger – but at the phalanges level? Hmm…

You know what, let’s just put down “small to mid-sized terrestrial mammal” and call it a day, yeah?

Theorising Thedas: The Bog Unicorn

“Another series, Alex? Don’t you have enough to write about?” Yeah, well, I’ve also been playing a lot of Dragon Age: Inquisition so excuse me if I have a lot to say about archaeology in the video game series. “Theorising Thedas” will be a look at how archaeology plays a major role in the conflicts of Thedas, the world in which the Dragon Age series takes place. We’ll also be looking at examples of real world archaeology within the series – like today’s topic, the Bog Unicorn! Content Warning: Some images of preserved human remains are below.

Dragon Age™: Inquisition_20180122194159
The Inquisitor atop the Bog Unicorn, a DLC mount available in Dragon Age: Inquisition.

In the 2014 video game Dragon Age: Inquisition, you play as the Inquisitor who heads the latest Inquisition against an army of demons and heretics. As the leader of such a massive organisation, your character is able to get supplies and aid from all corners of the world of Thedas, including some incredibly fantastic and exotic mounts. One of these mounts is known as the “Bog Unicorn” – a horse that had been preserved in a bog environment that has been brought back to life by the sheer power of the spirit. Although the game does not go into much more detail regarding the backstory of the Bog Unicorn, the design of the mount somehow manages to hit a lot of really interesting points about the phenomenon of “bog bodies” in real world archaeology. So let’s break it down…

To start, what is a “bog body”? In short, it is a body that has been preserved within a bog due to the acidic and anaerobic conditions of the surrounding environment. Bog bodies have been recovered since the 17th century. Prior to focusing on the conservation of archaeological finds, most bog bodies were either discarded or, in some cases, ground up into a medicinal powder called “mumia” (Aldhouse-Green 2015).

There has been an observed phenomenon of recovered bog bodies across parts of continental Europe, with additional cases found in Ireland and Britain. Most of these bodies have been dated to around the Iron Age, and many have been observed to have characteristics that may reflect a violent death (sometimes referred to as “overkill”). This has led to one interpretation of bog bodies representing those who were killed as part of a ritualistic sacrifice or as a punishment (Giles 2009).

The design of the Bog Unicorn manages to convey a lot of detail about bog bodies without actual textual explanation. For example, let’s take a look at the physical appearance of the mount. The Bog Unicorn is not skeletal, but has what appears to be a dark, leathery hide covering its body. Its hair is also a strange, rust red colour.

As you can see from the photo above of an actual bog body, this is the typical appearance of organic material that has been preserved within a bog. Sphagnum, released once bog moss dies, is the agent that causes the “tanning” effect on any soft tissue – this is what causes the colouration in both skin and hair found on bog bodies (Aldhouse-Green 2015).

Another noteworthy detail in the Bog Unicorn’s design is the sword thrust through the horse’s head, creating the “unicorn” effect – this is perhaps a nod to another phenomenon in the archaeology of bogs and other watery environments. Water has often been considered a liminal space (in other words, a sort of boundary or in-between place), as well as a source of life. It is possible that the deposition of remains in watery environments reflects a belief in water as a pathway to the spirit world, or perhaps more indicative of cyclic beliefs in regeneration and fertility (Bradley 2017). Weapons and other artefacts have also been noted to be recovered as deposits from water – possibly used as proxies for the human body in a ritual? It should also be noted that many weapons that are deposited in this way are often fragmented or ritualistically broken, perhaps to mark a sort of “death” of the object (Bruck 2006).

To wrap this discussion up, let’s move on from the physical appearance to talk more about intent. The Bog Unicorn, in the lore of the game, is explained to be a restless force that has moved beyond death to serve again. In other words, the Bog Unicorn is between life and death, floating somewhere in the middle as a sort of undead creature. To represent such a force as a preserved corpse from a bog is actually quite fitting, especially when one considers how a bog body is basically suspended between life and death (or at least, decay). As mentioned above, watery environments appear to have been identified as a liminal space – bogs even more so, as they were sort of in between land and water. If we take into consideration that bog bodies were part of a “punishment” involving their ritualistic killing, it might be that this liminal space proved to be the final, posthumous punishment – unable to decay and “pass on”, these bodies were left preserved, floating in some natural purgatory. But even if that’s all conjecture, there is still something so perfect about having a Bog Unicorn, who is between life and death, this world and the next, be your spectral-yet-physical steed for a battle that takes place between our world and the spirit world.

Bones That Look Like Other Bones: A MiniPost About Rabbits and Hares

Note: Is it morbid to look at rabbit and hare skeletons on Easter? Maybe. But more importantly, please remember that caring for rabbits as pets is a commitment – don’t buy them as an Easter Day gift for kids if you’re not committed to caring for them! More information can be found here.

So, moment of truth: how long did it take you to realise that rabbits and hares are two different animals? I’m pretty sure I was hitting double digits in age before that dawned on me…embarrassing? Maybe. But it’s an easy mistake to make: rabbits and hares look extremely alike! And that’s not just limited to their outsides either…today’s mini comparative anatomy post is about the bones of hares and rabbits!

Good rule of thumb with differentiating between hare and rabbit bones is to look at the size of the bones – hares are generally larger than rabbits. This is definitely noticeable just looking at the skulls of a hare (on the left, above) and a rabbit (on the right, above).

Hares also have larger, stronger hind legs, which can also be easily seen when you compare these bones to rabbit bones – in the above photo, are two femora, with the larger and more robust femur belonging to the hare.

Despite being from different species, however, both rabbits and hares do share similar physical traits in their skeletons, with explains why some archaeologists may have some confusion when it comes to differentiating between the two (for example, compare the two tibia bones above – besides the difference in size, they’re rather similar!).

If you’re interested in more archaeological work on hares, check on the Exploring the Easter E.g. project undertaken by the AHRC and the University of Nottingham!

The Bone Collector: Building A Personal Reference Collection

Although I guess you can say I’ve been a zooarchaeologist for the past 3 years, I’ve still been a bit behind when it comes to my own personal reference collection. It’s not a necessity for zooarchaeologists, of course, but it’s always good to have – plus, it’ll become important if you go into consulting work.

Some of the bones in my personal collection – yes, those are takeaway containers.

Of course, let me be clear that I’m not hunting animals down for their bones! Many zooarchaeologists with their own collections often come across remains in various ways – out in the wild, from a local farm, or in my case, from the nearest grocery store.

Every zooarchaeologist has their own personal method of processing remains, so I’m sure some would disagree with my tips. But for those who are working with bones for the first time, here’s a few pointers on processing:

  • Getting to Bare Bones

There’s many different ways to get down to the bones, and the method you should choose will depend on what you have left of the animal. Dermestid beetles are a quick and easy way to deflesh animals, but due to upkeep, are best left to professionals and labs who need large quantities of remains. Large, fleshy and furry remains may be buried or kept outside in a protected area to naturally deflesh, but this will take longer than other methods (and you obviously run the risk of certain living animals making off with your bones!). One of the more common methods of defleshing is through maceration – leaving remains in a closed container of water over a period of time until defleshed. If you feel like giving up a slow cooker, you could also slowly simmer the remains until the flesh can easily be removed. Fair Warning: this will smell extremely bad.

  • Getting All the “Bits” Off

The above methods will get most of the flesh off and allow for easier removal of the “squishy bits” inside. However, the body is a frustrating thing and there will still be smaller bits of tissue stuck in crevices and hard-to-reach areas. I recommend using a toothpick or cocktail stick to get “bits” out of the smaller crevices – it will take some time and probably be a little gross, but you want to be sure to get all those bits off before storage.

Additionally, biological washing up liquid such as Biotex can be used to clean and loosen up bits of soft tissue by soaking the bones in a mixture of the washing up liquid and water for a day or two.

  • Degreasing the Bones

This is an easy step to miss! Its important to degrease the bones, otherwise they will get gross…trust me. I forgot to degrease some turkey bones and they ended up growing mould after a few days in storage. Yuck. probably the easiest way to degrease bones is by leaving them in a solution of water + dish washing liquid.

  • Whitening the Bones

As a zooarchaeologist, I don’t really care much about whitening bones (I have never seen a white bone in my life, except for cremated bone fragments). If you do want to whiten your bones, however, most people suggest soaking bones in a mixture of hydrogen peroxide + water.

  • On Boiling and Bleach

When it comes to collecting bones, there are two bad “B” words: boiling and bleach. Both can damage and ruin your bones, so it’s best to substitute simmering for boiling and a hydrogen peroxide/water mixture for bleach.

That said…I am a very bad zooarchaeologist who has often boiled bones from animals that have already been cooked in order to 1) get all of the remaining meat and bits off and 2) make a nice bone broth to use for soups later on (blame my grad student thriftiness – nothing gets wasted!). I will still do a final wash of these bones with water + biological washing up liquid and degrease after boiling. These bones are usable, but they certainly don’t look as nice as my non-boiled bones and definitely have some damage, so I would suggest you don’t boil them. That said, it is possible to salvage the bones if you have already boiled them.

And a final important note: many countries have different laws regarding the collection of remains from certain species – make sure you double check that you can legally collect and keep the bones you have!

Studies in Skyrim: On the Chopping Block

Content Warning: Photo of human remains included in this post.

To start off our Studies in Skyrim series, I figured it would be best to begin with the beginning of the game itself! After all, what’s more fun than learning a bit about decapitations?

In Skyrim (Bioware 2011), capital punishment usually consists of a swift beheading – this is seen in the game’s opening, where you watch as a Stormcloak, deemed to be traitorous to the Empire, is beheaded by the Imperial army’s executioner. You luckily manage to escape the blade thanks to a dragon, but a similar execution is stumbled upon again in the town of Solitude.

In real life, decapitation has been a form of capital punishment for ages, with archaeological evidence of intentional beheading dating back to the later prehistoric – although it can be argued that some instances could have been part of ritual sacrifice as well (Armit 2012). Decapitations in antiquity (read: ancient Greece and the Roman Empire) were often used for citizens, especially of higher status, as it was seen as a more humane and less dishonourable punishment. This would possibly be accurate if the executioner was skilled and could deliver a quick and clean decapitation in a single blow of the sword or axe. This would change, of course, with the popularisation of the guillotine for beheading (Clark 1995).

The British history of decapitation as capital punishment goes back centuries and is too long to properly discuss in a blog post. Anglo-Saxons originally used decapitation to punish more serious offences of theft, but eventually this practice was reserved for those of noble and high status who have committed acts of treason (Dyson 2014). Arguably the most famous cases of beheading in Britain belongs to Catherine Howard and Anne Boleyn, two of King Henry VIII’s many wives. These executions were part of the seven that were done privately in the Tower of London (Clark 1995).

Decapitation is still used as capital punishment in some places to this day, but has mostly been abandoned as a practice in most parts of the world, although only relatively recently – for example, it was still used for capital punishment up until 1938 in Germany (Clark 1995).

So, how do we discover decapitations archaeologically? Isn’t it common to find skeletons disarticulated (or not together) once excavated? How do you differentiate between skulls from the beheaded and skulls from the dead?

Evidence of decapitation can sometimes be seen spatially, through the methods and locations of burial. In some places, such as Roman burial sites, there were no observed difference between decapitation burials and more normative burials. In the later Anglo-Saxon period, however, decapitation burials were moved to “execution cemeteries” to reflect a cultural understanding of decapitation as a “deviant burial” that should be kept separate from other burials (Dyson 2014).

The best place to look for evidence for decapitation is on the vertebrae – a beheading that has been done correctly will usually leave cut marks on the cervical vertebrae, which make up the neck. More unfortunate decapitations that required several more blows for a successful separation will also show related cut marks on facial features, such as on the mandible (Carty 2012).

Doctor, Doctor, Gimme the News: Bone Assessments in Zooarchaeology

Today I wanted to give you all a sneak peek into my current work – although I will admit that this is a bit more of a mundane part of my research. But zooarchaeology isn’t always exciting…sometimes it’s playing Bone Doctor and assessing bags and bags and bags and bags of bones!

Bags and bags and bags o' bones

Last week, I’ve spread over one hundred bags of bones across three desks. Why? Well, on one hand I like showing off my assemblages and work to my fellow PhDs in the office. But I also find it the easiest way to place everything in order of context.

Again, you may ask…why?

Bone assessments are quick (well, relatively speaking, I guess!) ways to, well…assess your bones! Prior to an in-dept investigation, a bone assessment allows me to get a general idea of what kind of animals may be represented in an assemblage, how the bones look, how they’ve been preserved, and how they’ve been treated. Of course, I’ll be doing a more focused identification and examination of each individual bone later on, but these bone assessments are a great way to get an idea of what I’m looking at.

Bone assessment form

Walking around my bags and bags of bones with a clipboard and bone assessment forms in hand kinda makes me feel like a doctor, really! Well, I guess in this case I’d be a veterinarian…and a really bad vet if I’m working with dead animals.

Basically, with these forms I sorta sketch out a picture of the assemblage – what sort of animals can I identify by eye? How many? What parts of the body do they represent? Listing things like colour, preservation, and characteristics like gnaw marks or butchery also allows me to get an idea of what these remains may have possibly been the result of. Is there many instances of gnaw marks from a large predator? Maybe these remains mark the end of one of their prey! Is there many butchery marks and charred bone? Perhaps this is the remains of a feast!

Yes, the chicken scratch you see here is my handwriting…I guess that really makes me more of a doctor, huh? The photo above is me attempting to make sense of the bone assessments – this includes tallying up total numbers of animal and element identifications, giving a (very) rough chronological order of the context numbers, and listing out the major characteristics I saw in each period. This way, I can really visualise the shifts and patterns that the assemblage forms as time passes from one period to the next.

I know this wasn’t the most exciting post this blog has seen, but I want to show off all aspects of zooarchaeological work! And that includes some of the less exciting things…however, I think bone assessments are really interesting – they almost give you a sneak peek into whatever you’re about to dive into for the next year or so! And while I don’t want to get into too much detail…I think this is going to be a really exciting and interesting assemblage of animal bones.

A Thanksgiving Blog Post Without Turkeys, ‘Cos I Don’t Have Any Turkey Bones

As an American, I feel a bit obligated to make a themed-post for Thanksgiving. But here’s the problem: I don’t have any turkey bones in my collection.

So, what’s a zooarchaeologist blogger to do? Well, the next best thing: here’s a minipost looking at the bones of domestic fowl and why it’s important to differentiate between domestic and wild birds in an archaeological assemblage.

Have a happy Thanksgiving, fellow Americans!

In zooarchaeology, domestic fowl usually refers to domesticated species of birds such as chickens, turkeys, and guineafowl. Of course, this can vary greatly depending on the regional and temporal contexts of an assemblage.

Differentiating between domesticated and wild birds are just as important as differentiating between domesticated and wild mammals. This gives us a better idea of what kind of food and other animal products accessible to the inhabitants of a site, as well as what may have been hunted (and in some cases, gives us an idea of the technology needed to hunt!). If it’s more of a funerary or ritual context, bird remains (especially ones that have evidence of human modification) may also help us better understand beliefs of the past!

Chicken

Probably the most pervasive domestic fowl across the world, the chicken is probably one of the most identifiable bird bones out there due to how different their bones look in comparison to most other birds. I always associate chicken with this rounded look, in contrast to the sort of sharp, edged look that other bird bones have.

There is a current interdisciplinary project going on looking at the social, cultural, and environmental impact of the chicken called the Chicken Project.

Bantam

“Bantam poultry” usually refers to chicken or ducks that have are different breeds from what we normally call chicken/ducks, resulting in some morphological differences. The bones above are from a game hen, which is the closest thing I have in my collection to bantam (I do have a bantam chicken as well, but it’s currently being decreased!).

Compare those bones to the chicken bones above – See the difference in rounded bone versus sharp bone?

Guinea fowl

Guinea fowl are native to parts of Africa, but have been introduced elsewhere as domesticated fowl. Apparently it’s a bit similar to turkey, but I’ve never eaten it myself (feel free to let me know what it’s like if you’ve eaten it!).

Differentiating between something like bantam poultry and guinea fowl would be a bit difficult, as you can see – there’s certainly some similarities in the size and shape of bones! However, I’d argue that guinea fowl bones have a been more thickness on them, but to be fair I’ve rarely had to work with them in my projects in Scotland.

Geese

Geese are not always considered domestic fowl, but depending on the region and context of the site, it’s a possibility. I figured I would throw it in here for fun, though!

The size and thickness of goose bones is a good indicator for identification, especially in comparison to most other bird bones. Especially if you have the skull – that bill is a dead giveaway! Although it’s easy to confuse with a duck.

Bones That Look Like Other Bones: A MiniPost About Rodents and Fish

Yet another minipost in my comparative anatomy series! But this one might be the strangest paring of all.

Rodents and fish – could there be any more different animals? And yet, I find that students just starting out in archaeology tend to confuse the two together. To be fair, it’s very understandable – the size of rodent bones can be comparable to the size of many fish bones. So let’s break it down and see how different they really are.

Rat and Fish Cranium

For starters, let’s look at the cranium of a rat (left) and an Atlantic cod (right). As you can see, most elements of the skeleton look completely different. The rat has the sort of skull you would expect to see with any animal, while the fish…well, fish are basically made of a head and a tail, so most fish bones you find will be part of the cranium. As I’ve mentioned before in my previous post on fish bone, they will also have a different sort of texture and look compared to mammal bone – in my opinion, its a very “fish-like” texture, a bit shiny and flaky. Always a good giveaway that you’re dealing with a fish!

Rat and Fish Vertebrae

So how is it possible to even confuse the two? Well, let’s look at something a bit trickier…here’s the vertebrae from a rat (left) and from a fish (right). Now, if you don’t know that there’s a difference in shape between rat and fish vertebrae, you might not be able to differentiate the two right away. And given how weird vertebrae can be in varying shapes between types of vertebrae in an individual body, who knows! Maybe they’re from the same animal?

Luckily, there is a visual difference between the two. Rat vertebrae look relatively similar to any other mammal vertebrae (“relatively” being the key word here, of course…but talking about the differences in mammal vertebrae is a post for a different day!). Fish, on the other hand, have very distinct-looking vertebrae and vertebral bodies. Unfortunately, distinguishing between the two can be more difficult if the vertebrae are more fragmented – I’ve seen many students get the two confused if most of the vertebral arches and “wings” are missing.

“But Alex!” I hear you say, “these bones look so different, I don’t believe that anyone could get them confused!” Okay then…let’s take two random, slightly fragmented bones from a herring and a mouse then, shall we?

Can you tell the difference?

As you can see, it can get tricky! Fragmentation, size, preservation of bone – these are variables that you encounter with archaeological bones that make things a bit more challenging than you’d think! The best way to get better, of course, is to practice, practice, practice. It gets easier…

…well, eventually.
