I have also finally moved over to the other site, if anyone wants to connect over there you can find me at alexrdpayne.bsky.social

Happy to share our new study published today at Proceedings B! 🐊 @RSocPublishing @SebastianHoehna 📝 “The effects of cryptic diversity on diversification dynamics analyses in Crocodylia” royalsocietypublishing.org/doi/10.1098/rs… #crocodylian #species #macroevolution 🧵 (1/7)

(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 😀 tandfonline.com/doi/full/10.10…

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. #Paleontology" target="_blank" rel="nofollow noopener">peerj.com/articles/18519… #EthicalIssues

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. anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

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 tandfonline.com/doi/full/10.10…

Finally out! S. Sánchez-Fenollosa (@DinopolisTeruel ), F. Escaso (@UNED ) and A. Cobos (@DinopolisTeruel) published in the @ZoolJLinnSoc a new specimens of #Dacentrurus armatus from the Upper Jurassic of #Teruel! doi.org/10.1093/zoolin…

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. journals.plos.org/plosone/articl…

It is a pleasure to announce for this #FossilFriday that we have a new friend in the paleocommunity, 𝙊𝙥𝙝𝙞𝙪𝙨𝙨𝙖𝙨𝙪𝙘𝙝𝙪𝙨 𝙥𝙖𝙞𝙢𝙤𝙜𝙤𝙣𝙚𝙘𝙩𝙚𝙨, a new goniopholidid crocodylomorph from the Jurassic of Portugal.

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. 1/9

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/10.1111/ge… existing global datasets, she shows how humans are changing #biodiversity. 1/4

@ArminReindl All your silhouettes are fantastic, always know they're going to be great quality when I see your name attached!

OH YEEEES ITS MY BOY

@portraitonfire1 @NatureEcoEvo @drkatiedavis @pdmannion @GraemeTLloyd Thank you for being so supportive throughout! 🥳

@AlexRDPayne @NatureEcoEvo @drkatiedavis @pdmannion @GraemeTLloyd I’m so proud of you! Watching you work on this over the years, to actually having it published, what an amazing job ❤️👏

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/s4155…

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/s4155…
