New paper out today! Led by Daniel Schwarz, we retrodeformed the skull and reconstructed the cranio-mandibular musculature of the giant stem-amphibian Mastodonsaurus giganteus. Our results show that Mastodonsaurus had a powerful bite and a crocodile-
like bite-and-hold feeding style.

Heyy, I finally landed on Bluesky ! 👋

For those who don’t know me, I’m Arnaud, PhD student in Palaeontology and diving into all kind of bromalites (fossilised digested content) ! 🦴💩

I will post research updates here and also other stuff I do !

Looking forward to connecting with more people here !

Bird feathers from a Late Cretaceous coprolite
O’Connor et al. describe a Cretaceous coprolite preserving feathers. Bone fragments suggest they are from a hesperornithiform bird, consistent with feather morphologies associated with reduced water p...

Paleontologist and author on the study Arnaud Rebillard joined Science Friday to talk about how vomit becomes fossilized and why scientists are so excited to study it. Listen to the full podcast now: www.sciencefriday.com/segments/hyd...
Earth's Ancient Hydrogen, And Fossilized Vomit
A new simulation shows large amounts of hydrogen in our planet’s core. And, what scientists found in 290-million-year-old vomit.
