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.
Huge thanks to NCN for funding, and to my coauthors
@sergilopeztorres.bsky.social and others for their help ! The paper (soon in OpenAccess) is available here : onlinelibrary.wiley.com/share/author...
We describe shell fragments, and a skull that we attribute to Trionyx cf. vindobonensis. This is interesting both for the paleobiogeography of the family during the Miocene, and also because it opens up the possibility of a northern dispersal of such taxa during this period.
These findings come from new vertebrate localities from the Holy Cross Mountains region, Central Poland. They represent a coastal environment along the Parathethys, about 12 Ma (Serravalian).
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.

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
New paper on the notosuchian Eremosuchus by @piginatutu.bsky.social, co-authored by myself and @pdmannion.bsky.social among others out now!! We even find some cool evidence of replacement teeth in the dentary! www.tandfonline.com/doi/full/10....
A brown running Hamadasuchus
The Kem Kem was home to a few terrestrial crocodylomorphs, and the 2m-long predator Hamadasuchus is one of the more intimidating ones!

Great #SVP2025 in #Birmingham 🇬🇧! As always, an excellent chance to collect feedback and reconnect with collaborators! #WarsawTeam
🐢 Grateful to be part of this amazing community of turtle researchers at #2025SVP. Feeling energized from the incredible presentations & discussions. Thank you all for the insights, support, and shared passion for these fascinating critters. Here’s to more turtley collaborations & discoveries ahead!
Check out this new paper about crocodylian, likely mekosuchine, eggshell fragments from the Eocene of Queensland. Great to see this material finally published.

We had an excellent research visit at the Henryk Teisseyre Geological Museum and the Department of Paleozoology at the University of #Wrocław. Excellent #Miocene fossils and a few surprises! @yohanpochatcot.bsky.social @ncn.gov.pl
@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
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.
Size comparison and skull reconstruction of Orientalosuchus naduongensis, a fairly small crocodilian from the Eocene of Vietnam.

Beautiful cover paleoart by Guilherme Gehr
A big thanks to all my co-authors, as well as the editor and reviewers, and all the curators that made this work possible !
Feel free to DM me if you want the PDF :)
The phylogenetic signal, although existing, is quite moderate, and sadly cannot be 'translated' into relevant morphological characters. This study will be useful and raises several problems for the inclusion of fossil forms, to study ecological changes for example.
Through a very thorough sampling of extant crocs (111 specimens of diverse ontogenetic stages and taxa) we show that the morphology of the endosseous labyrinth is mainly related to the size of the specimen (allometry) and probably to changes in braincase conformation.
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

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

Glad you noticed, I admit this was more about displaying the closest overall body shape possible for each clade than anything else :) Happy that you like the paper and thanks again for making your work available to the community 🐊🐊
Thanks to people that proofread the manuscript, and
@anatrecord.bsky.social
for the great Special Issue this is a part of. PDF is also available for free here: www.researchgate.net/publication/...
I tried to put in as much references as possible, summarizing decades of research, so a good place to start to get interested in this group, or (hopefully) to get a global overview.
New #crocpaper alert ! 🐊🚨 Fossil crocodylomorphs lived in a wide diversity of environments compared to extant ones. This review (my first one !) focuses on those adaptations, from very early Triassic forms to crown group eusuchians ! doi.org/10.1002/ar.2... in
