Publikacja naszych badaczy z @IBE_Warszawa w Journal of Anatomy opisująca pierwsze skamieniałości żółwi trójpazurzastych wykazujące, że obszar dzisiejszej Polski w miocenie stanowił część dynamicznego północnego zasięgu fauny ciepłolubnej oraz ważny element szlaków migracyjnych.

What a better way to start the New Year than with a new publication ? I am very glad to introduce the first paper linked with my current post-doc at @ibe-warszawa.bsky.social. We describe the first trionychid remains from the Middle Miocene of Poland, in @journalofanatomy.bsky.social.

🐊 Largest survey of skeletal disease in living crocodilians! Nearly half showed osteopathologies, w/trauma most common. Skulls were hit hardest, and non-traumatic issues like inflammation and joint degeneration rose w/size & age. Cornille et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Our paper re-evaluating the notosuchian Eremosuchus elkoholicus is out now! This work formed a chapter of my PhD thesis, and sheds some light on the complex evolutionary history of sebecid crocodyliforms 🐊🌎 @es-ucl.bsky.social

The Kem Kem was home to a few terrestrial crocodylomorphs, and the 2m-long predator Hamadasuchus is one of the more intimidating ones! Size comparison below ⬇️ #sciart #paleoart

@yohanpochatcot.bsky.social studied the variation of the morphology of the endosseous labyrinths of extant crocodiles & showed that its morphology is mainly related to the size of the specimen (allometry) and is probably due to changes in braincase conformation.

Size comparison and skull reconstruction of Orientalosuchus naduongensis, a fairly small crocodilian from the Eocene of Vietnam. #sciart #orientalosuchus #crocodilia
A size comparison between a human and Orientalosuchus naduongensis. Orientalosuchus is shown with a long tail, for relatively short legs and a short and rounded snout. It is shown as somewhere around 1.7 to 1.8 meters long. A map on the side shows where it was found in Vietnam.A skull reconstruction of Orientalosuchus naduongensis with a 3cm scalebar. It has a short and rather wide snout with large eyes and prominent crests that run between the opening of the nares and the eyes.
