New findings in Science suggest that rodents owe much of their evolutionary success to their thumb-nail (the first digit, D1), an adaptation that gave them dexterous hands for cracking seeds and nuts. Learn more in this week's issue: https://scim.ag/46caVho

Huge thanks to @palaeopercs.bsky.social for inviting and hosting me! If you missed my talk on Tuesday, you can now catch up via their YouTube channel 👇 www.youtube.com/watch?v=x19X...

New paper in which we evaluate how we can use information on past extinction events to better contextualise the ongoing anthropogenic extinction, led by @anthropocenebio.bsky.social (with @bethanyjallen.bsky.social, @inesismartins.bsky.social, & others): onlinelibrary.wiley.com/doi/10.1111/...

Our paper on rodent thumbnails is out! Big team effort, powered by museum collections. Turns out, nails can reveal a lot about rodent evolution. Shoutout to Dr. Gordon Shepherd for the wild idea to study rodents thumbs!

You can be proud! They were all amazing!!! 🤩

No, it is not a dream. This actually happened!!! We had a *fantastic* #CPEGCPB26 meeting and I cannot articulate any other adjective to describe it until I recover from it. Thanks to everyone who attended and everyone who helped making this happen. @kristinakocakova.bsky.social

Fóssil de tartaruga marinha de 50 milhões de anos é o primeiro vertebrado fóssil nomeado na Síria. A Syriemys lelunensis recua a origem do grupo Stereogenyini em mais de 10 milhões de anos

We are honored on #FossilFriday to receive an Apex publication award for our Special Issue on comparative and functional anatomy of Triassic tetrapods: anatomypubs.onlinelibrary.wiley.com/toc/19328494... Editors Felipe Pinheiro, Flávio Pretto & Leonardo Kerber. Cover artwork by Márcio L. Castro

Aaaaand, on the top of all that, @fernandalandim.bsky.social won the best standard talk prize!!! 🤩🤩🤩🥹🎉

Proud supervisor moment! 🥹🤩 So incredible to watch our undergrad students from the lab shine in front of such a knowledgeable audience at @cpeg-cpb25.bsky.social. They absolutely crushed it and I couldn’t be prouder! @fernandalandim.bsky.social, Anna Clara Annes, Jorge Silva and Gabriela Karam.

Super proud of our lab students for their final course presentations: Luan Estevão defended his MSc on elasmarian ornithischians; Kamila Lima presented a poster on her undergrad research in conservation paleobiology of freshwater turtles; and @fernandalandim.bsky.social and Pedro Kenji+

Can we just take a moment to appreciate turtle skeletons? 🐢🦴🤯 The original model of this gopher tortoise skeleton on Sketchfab (skfb.ly/ooVZS) is a crowd favorite & I've received requests for a downloadable version lately, so I uploaded a new one to MorphoSource: www.morphosource.org/concern/medi...

I'm a bit late, since we were away for fieldwork, but check out our new paper on data equity in paleo, led by the amazing @emmadnn.bsky.social.

Delighted to share our paper on data equity in #palaeobiology as part of Paleobiology's 50th anniversary issue 🥳 We look at how palaeo data is collected, stored, curated & shared, and how equity in these processes is crucial for our field's future (1/n) 🧪⚒️ doi.org/10.1017/pab....

The MacroPaleo Lab has officially hit the field for the first time! It was tough, thrilling, and packed with adventure. Huge shoutout to our incredible field crew! Stay tuned—some fascinating discoveries are coming your way! 🦴 🦖 🪨 ⛏️

Congratulations to my friend Diego Pol for his well deserved induction into the Argentine National Academy of Science!

Me and @richardjbutler.bsky.social have a new review paper today in which we make the case for the importance of systematics, taxonomy and fieldwork in palaeo. You should read it: you'll like it royalsocietypublishing.org/doi/10.1098/...

My first post on here, so I’d like to share some cool things that have happened recently: 1) Last week I successfully defended my PhD thesis, and am a (pending) croc doc 🐊 2) I now share my name with a caterpillar cake 3) I learnt the importance of never being photographed with a whiteboard

Happy #FossilFriday! We’re excited to share our new preprint from the @palaeoverse.bsky.social team “Ten simple rules to follow when cleaning occurrence data in palaeobiology”, available now from EcoEvoRXiv: doi.org/10.32942/X2F... With a bonus accompanying vignette! tenrules.palaeoverse.org

Pedro wrote a great thread for our last pub about the Pleistocene bush dog, so I will just repost it. Check it out!

Check this awesome contribution I was honored to be a part of. #Fossil #canids FTW

Yes! Another AMAZING paleoart by Júlia d'Oliveira just dropped! It showcases the Pleistocene bush dog (Speothos pacivorus) from Brazil, in association with our new paper published in JVP (link below 👇). tandfonline.com/doi/full/10.10… Follow the 🧵

PhD project opportunity here in Manchester to do some cool inter-disciplinary stuff on the taphonomy and fossil record of collagen. Ancient, recent, modern, lab-work, theoretical, data, imaging, its all there! Deadline Jan 31st www.findaphd.com/phds/project...

Super happy to have visited this amazing museum and research center (Centro de Investigaciones Paleontológicas) in Villa de Leyva, Colombia. The fossils are l impressive, as well as the exhibition itself! Hope to come back, at some point. 🇨🇴🦖🦴

For the first #FossilFriday of 2025, here's my annual thread looking back on the #temnospondyl research that came out last year! In general, papers were skewed towards anatomical descriptions of specifically European taxa that were predominantly from Triassic deposits. 🧵👇 (1/30ish)

Not perfect, but not bad. Learned some important lessons. Next will be better!

Check out the mesmerizing moment - a crocodile embryo hatching from its egg! 🥚🐊 Our new research in @natureportfolio.bsky.social reveals how compressive forces, rather than gene interactions, sculpt their intricate head scales - learn more here ⬇️ www.nature.com/articles/s41... 🧪

🚨Hyped to share our new article in @natureportfolio.bsky.social! We show that crocodile head scales develop from compressive folding that arises from constrained skin growth 🐊🔬 Really proud of this one - it's cool 😎 Please read & share! 🧪 @genevunige.bsky.social www.nature.com/articles/s41...
