OH HEY THERE I’m Yara the Osteological Oligarch, and my face just got distributed across Berlin!!

So let me tell you a little about my PhD research on bone evolution (and bonus fossil virus evidence) in English! 🦠 🦴 💀 ✨

#Osteology #SciComm
Seriously tho..
MOM LOOK IM CENTERFOLD!!

My mother can’t read german.. I can’t read german.

It’s titled “the time traveler”.. either millions of years back or a year forward are my options tbh

But if you CAN read german here is the link: museumfuernaturkunde.berlin/sites/default/…
Ahem.
So I tweet about all kinds of natur-y things, many of you might wonder whats she actually study?

Right now, B O N E S🦴

While this was mostly for the 📸 I DO rely heavily on mammals for my research because humans and mice have been studied the most on a bone-cell level!
Basically I want to see if these mammalian “standards” apply across and DOWN the tree of life!

Do the bones of fish, frogs, reptiles, and birbos do the same things as mammals? If so, when did these features evolve? TO THE FOSSILS!

*intensly models ice age frog bones*
I’ve been looking at some of the earliest skeletonizing vertebrates and it may surprise you to know that bone 🦴 and dentine🦷 both often played interchangeable roles in early skeletons!

That’s RIGHT our teeth tissues and our bones tissueslikely share a very intertwined history!
Ah there you gar! A great example of tooth-y tissues that are NOT in the mouth is found in fish like this fossil Gar.

✨ that shine comes from an enamel-like tissue that coats ganoid scales! This makes for gorgeous preservation ✨
In fact some early fish healed their bones with dentine! Tooth stuff to heal bones with!?

Early vertebrates we’re just flexing all their new found adaptations

And it looked very very different from what we have today!
By understanding how bones work in different animals (read hella extinct) we can tell more about our past.

If you understand how bones grow and heal you can tell when it’s gone wrong and why!
For example evidence for possible viral infection 🦠 👇🏽
Big thanks to the @mfnberlin for giving me this platform and big thanks to the photographers who made me comfortable in my own skin!

TLDR: you should follow me because I will show you weird animal skeletons and talk about evolution of bone!!

Mostly I need you to know that #BlackLivesMattter still, and wear a mask STILL.
