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

A new Upper Franconian ichthyosaur species has been discovered from Mistelgau. Learn all about it on the @pensoft.net blog!

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...

Nearly five-meter-long slab of belemnite battleground with skeleton of Eurhinosaurus mistelgauensis – the inspiration for the beautiful artwork by Andrey Atuchin in my previous post. Specimen is from Mistelgau, excavated by and curated at Urwelt-Museum Oberfranken in Bayreuth, Germany

The study was conducted by @spichergael.bsky.social & colleagues (@feikosaur.bsky.social) & published today in @mfnberlin.bsky.social's Open access journal Fossil Record. Congrats to all authors! It's available here: fr.pensoft.net/article/1542...

Fossil & artwork to be exhibited at UMO in future.

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.

The newly described and well-preserved fossils represent the youngest known occurrence of Eurhinosaurus.

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 β€”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! 🀩

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 ...

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 πŸ‘‡ for some highlights

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.
