(1/n) 🚨Croc paper alert ! It's finally out!
Please welcome Thilastikosuchus scutorectangularis 🐊 the first crocodyliform from the Sanfranciscana Basin, Brazil!
I'd like to thank Joyce for inviting me to collaborate, I had a great time 😀

The monstruous alligatoroid Deinosuchus is famous for fossil evidence of having preyed on hadrosaurs and tyrannosauroids, although it seems to have preferred sea turtles. Compared to modern crocodilians, it had a massive skull, even relative to the enormous rest of the skeleton.

It's been a little while since I last posted any art here, here is the colour scheme I designed for Torvosaurus tanneri - definitely one of my favourite Jurassic theropods!

I’m pleased to share the release of the third paper in my thesis, which I successfully defended last Friday. This chapter critically examines the methodology in DePalma et al. (2021) on the seasonality of the End-Cretaceous extinction.

New Peirosauridae from Brazil just dropped! 🚨🐊
Meet Epoidesuchus tavaresae, from the Adamantina Formation (Late Cretaceous), a new pepesuchine peirosaurid, which was long-snouted and semiaquiatic.
The great paleoart below was done by Guilherme Gehr.

I guess we are returning to what is either the most successful, or over-lumped, taxa in all of #Crocodylomorpha. #Araripesuchus, which has just added another new species - A. manzanensis

Please welcome Ichthyotitan severnensis, a gigantic ichthyosaur from the latest Triassic of the UK!
The key - holotype - specimen was found in 2020 by fossil-hunting father-daughter duo Justin and Ruby Reynolds (Ruby was then 11!), who are co-authors.

My paper, describing a new genus and species of lobopodian, has just been published.
Mobulavermis adustus is a large relative of Kerygmachela and Utahnax. For those who can't access the paper, I will the findings summarize below.

Great to see the first paper coming out from Shuyu Deng's PhD today: "Human modification of land cover alters net primary productivity, species richness and their relationship" onlinelibrary.wiley.com/doi/… existing global datasets, she shows how humans are changing #biodiversity. 1/4
ALT A graph showing Net Primary Productivity (NPP) in relatively natural vegetation types against the NPP difference between the natural and human modified systems. In places with low initial NPP human modification increases NPP, in places with higher initial NPP it decreases. Major modifications have slightly more extreme effects than minor ones.

Thrilled to be able to share this finally! Our paper is out in @NatureEcoEvo, exploring how biotic and abiotic factors shaped the evolutionary history of crocodile-line archosaurs. Huge thanks to co-authors @drkatiedavis, @pdmannion and @GraemeTLloyd! nature.com/articles/s41559-0…

New paper @NatureEcoEvo led by @AlexRDPayne & @drkatiedavis, with @GraemeTLloyd, in which we show how the interplay of biotic abiotic drivers shaped the 250 million year history of crocodiles their extinct relatives: nature.com/articles/s41559-0…

🐊🐊🐊Did you know that crocs started out as agile, land-living critters that looked more like foxes🦊 than “lizard-like” reptiles🦎?

Aetosaurs and their size mystery! New find in Petrified Forest National Park, Arizona, reveals a colossal Typothorax coccinarum, twice the size of others. But size ≠ maturity! New study by @chinleana, William Reyes & @NotThatMarsh: doi.org/10.1002/ar.25343
