New Jurassic ichthyosaur species discovered in Mistelgau
Ichthyosaurs were marine reptiles, with dolphin-like bodies, that lived during the time of the dinosaurs.

Eurhinosaurus mistelgauensis is interesting because it is quite a bit younger than all other known Eurhinosaurus species. It gives us vital information of these ichthyosaurs close to the Middle Jurassic faunal turnover. Art: Andrey Atuchin, used with permission from Urwelt-Museum Oberfranken

A new Eurhinosaurus (Ichthyosauria) species from the Lower Jurassic (Toarcian) of Mistelgau (Bavaria, Southern Germany)
Eurhinosaurus is a European Lower Jurassic longirostrine ichthyosaur, characterized by its remarkable overbite. Despite the long history of the genus, the taxonomy of Eurhinosaurus is still under deba...

News @ Urwelt-Museum Oberfranken (UMO) in Bayreuth: new ichthyosaur, Eurhinosaurus mistelgauensis, named today after UMO's prime excavation site, the Jurassic clay pit Mistelgau. @olorotitan.bsky.social beautifully reconstructed the to-be fossil on a belemnite battleground typical for the locality.

Got to Lyon yesterday! Here to dive into some Late Jurassic turtles. 🐢time to dust off fossils that haven’t been touched since the 1800s!

Spent the whole week working on a beautifully preserved Eurysternum wagleri. 🐢 First stop: Ann Arbor for CT-scanning —huge thanks to @friedmanlab.bsky.social for the warm welcome, taking the time to scan the specimen, and inviting me to give a short talk on my PhD research #FossilFriday

Just submitted a huge manuscript (nearly 30,000 words!) with a fantastic team! It’s a detailed descriptive study of a well-known Jurassic ichthyosaur, a deep dive into its anatomy. Can’t wait to share it with you all soon! 🤩

My PhD student Guilherme Hermanson & I have a new paper out today in Ecology & Evolution! 🐢🤩
We think the morphologically conservative body plan of turtles can in part be explained by allometric constraints imposed by the shell. Thread 👇 for some highlights

Shell Constraints on Evolutionary Body Size–Limb Size Allometry Can Explain Morphological Conservatism in the Turtle Body Plan
Turtle body size and limb size scale nearly isometrically along the group's evolution, although major deviations are only seen in highly specialized ecological or morphological groups. The evolution ...

Hi Bluesky!
I’am doing a PhD in paleontology at the Jurassica Museum and University of Fribourg. My project focuses on the diversity of thalassochelydian turtles 🐢 (such as this skull of Solnhofia brachyrhyncha). I'm also working on other fossil turtles and marine reptiles such as ichthyosaurs.
