@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.

🚨Croc paper alert!

Please welcome Thilastikosuchus scutorectangularis 🐊, the oldest notosuchian from South America and the first crocodyliform from the Sanfranciscana Basin, Brazil!

Happy to be part of this team. Huge thanks to Joyce for being invited to collaborate! #paleontology
Anatomical description and systematics of a new notosuchian (Mesoeucrocodylia; Crocodyliformes) from the Quiricó Formation, Lower Cretaceous, Sanfranciscana Basin, Brazil
Notosuchians comprise a clade of mostly terrestrial crocodyliforms generally found in Cretaceous Gondwanan deposits. They evolved into many forms and some species show convergences with mammalian f...

New #crocpaper alert !🐊🚨 And just in time for Christmas ! We studied the variation of the morphology of the endosseous labyrinths (inner ears) of extant crocs. Published in @journalofanatomy.bsky.social

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the...

Bust of Sebecus icaeorhinus. This is actually a test for a larger -Iberosuchus- project I am working on.
Sebecosuchia was really something.
