Hello Bluesky! My name is Jorgo Ristevski, and I am a paleontologist that studies crocodylomorphs.
A great summary by Adam Yates on the "drop croc" topic. In short, there is no evidence to support tree climbing in any mekosuchine crocodylian.
Also, using AI generated articles to further promote this unsubstantiated idea is a really bad look.

@jorgoristevski.bsky.social just alterted me to this absolutely horrible page of false AI slop being passed off as an educational page on the Queensland Museum website.

Australia’s oldest crocodylian eggshell: insights into the reproductive paleoecology of mekosuchines

Happy #FossilFriday! Meet Paludirex, a BIG #crocodile from #Australia, one of many crocs coming from the Science Museum of Minnesota to @badweatherbrew.bsky.social for #CroctoberFest tomorrow (Sat, Sept 20)! We’ll be there 12-5pm with sooo much + I’m giving two talks, come raise a glass with us! 🐊🍺🐊

For #Croctober Day 20 I want to shout out some fun etymology. To the left you see Paludirex, a large mekosuchine who's name means "swamp king". On the right is Gunggamarandu, which translates to "river boss".
Both have been named by Jorgo Ristevski

For #Croctober Day 11 we got Confractosuchus (art by Julius Csotonyi)
Confracto once inhabited the Winton Formation of Australia, but unlike the tiny Isisfordia was sizable enough to even feed on dinosaurs. Which we know because we found the bones of an elasmarian in its stomach

Heres a fun one from a research history POV.
In 1997 researchers described a snout tip under the name Baru huberi and in 2016 skull elements were given the name Ultrastenos willisi
Only last year did we recognize that both fossils belonged to a single individual

CRACK!
Razanandrongobe easily crushes a dinosaur's femur to feed from its nutritious marrow
If Barinasuchus' skull rivaled the size of a Daspletosaurus, this crocodyliform's skull rivaled the size of a T. rex, and was arguably more specialized for bone-cracking

In the Late Triassic, croc relatives took on a broader array of forms and ecological roles than dinosaurs. The largest carnivores, for example, were big croc relatives like our chompy friend Fasolasuchus here. This life-size model is on display at Parque Nacional Talampaya, Argentina. 🧪
