looking nice today
Today in the woods I found nearly an entire skeleton— to what I think is one of my dad’s cows. My family now thinks I am the strangest person alive but nevertheless, I proceeded to dig up each piece and I brought back the pieces that were the least brittle to the house and scrubbed each bone with a brush and Dawn soap. Who knows what’s in store for these guys, but I definitely feel something in the works! I’m especially fascinated with the gigantic teeth I guess I just never envisioned cows having such huge teeth!
please someone can identify this
it’s driving me crazy
it’s definitely a coyote
thanks you all
THOSE TEETH! HANDS DOWN COOLEST TEETH!
Adaptive evolution is thrilling! Look how specialized! wonderful! crazy!
here’s the weird doe skull i found… i posted a forum question on the natural history museum website so hopefully someone will know what’s up with her there :/
hello! i was wondering if you might know what was wrong with this doe (roe deer)? i’m nearly sure it didn’t happen post-mortem, because the bone around the damaged areas is knitted weirdly, so would have happened when she was alive. i’ve tried to research deer bone diseases/cancers but i’m not having much luck, apart from lumpy jaw, but this is different :c she was elderly so it might be an age issue? here’s the question i posted on the nhm website, there are more photos attached:http://www.nhm.ac.uk/natureplus/message/30417#30417
thankyou very much for your time!
I am neither a pathologist nor a vet, so I can’t tell you definitively what happened to this animal, I can only offer conjecture and relay what I’ve seen in my experience. With older animals (and clearly, this was one very old animal), we see a lot of severe tooth wear and gum loss, resulting in dental impactions, abscesses, and infection. A symptom of a standard dental infection is also heavy inflammation and bone density loss. It appears to me that inflammation due to the impaction of plant material most likely caused the gum recession and bone loss, and thus the loss of teeth. Continual grinding on sensitive surfaces furthers the spread of infection.
Brush and floss your teeth!
The Brain Scoop: Episode 29
Chicago Adventure, Part III: Little Skeletons
Our third installment in the Chicago Field Museum adventures! In this episode, Andria blows my mind with some pretty impressive lettering skills, and we talk about a mammal with some of the most highly specialized teeth of any animal on the planet: the crabeater seal (it doesn’t actually eat crabs).
So…I drew a skull this past semester for my first digital painting project. Little by little, I think I’m starting to get the hang of this digital-thing - finally!
Cow mandible with honeycomb network of abcesses from actinomycosis infection. Actinomyces bovis is a gram-positive bacteria that leads to granulomatous abcessing of infected areas of the head and neck in cattle which can destroy bone. A rel…ated bacterium A. israelii causes a simillar but more rare condition in humans. In cattle the condition is referred to as “lumpy jaw.” Untreated, the infection will produce copious amounts of pus whichs discharges from the skin. Actinomyces were one thought to be a fungus because of their branching filamentous structures.

Human, Aye-aye, bat, frog, dolphin. Absolutely fantastic.
EDIT: I thought I should talk about this a bit more:
One of the things that fascinates me the most when learning about comparative anatomy is how we are all made of the same organs and bones, and it’s the special adaptations and morphologies these parts take on which make the most drastic differences between us as animals. The bones in a bat’s wing are the same bones that are in our hands, they just happen to be elongated and connected with a much thinner tissue membrane. Because dolphins don’t need individual fingers, theirs have grown together underneath a cohesive layer of fat, muscle and skin, adapting into paddles. Once you start to look underneath the surface of these creatures and study how their bones have changed shape, grown, or shrunk, it can really shed light onto how we all fit together in the bigger sphere. We can physically begin to see how we have changed over time.
