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…

New research offers a more complete view of Arthropleura’s background, opening the door to answering remaining questions about the arthropod’s diet and habitat. Learn more in this week’s issue of Science Advances: bit.ly/4dFc0j6

3D microCT scans show the full body anatomy of the myriapod Arthropleura science.org/doi/10.1126/sc…

EXTREMELY proud of our lab members for their participation in this year's Brazilian Congress of Paleontology! Lots of great interactions and possible new collaborations. And even a best presentation prize (congrats Thayara!) 🥹💚

Very proud of my first poster presentation at the Brazilian Congress of Paleontology! Lots of great interactions and fond memories of Maceió 💚 🥹

Great day for Mesozoic amphibians: tadpoles from the Jurassic stem-frog Notobatrachus show early origin of anuran metamorphosis. This is a fantastic fossil (look at those cranial nerves!) and highly consequential for amphibian origins research. nature.com/articles/s4158…

Ever wondered how giant Miocene crocodylians (e.g. Purussaurus and Mourasuchus) attained such large sizes? In this new paper led by PhD student Ana Laura S. Paiva, we show that climate of the Western Amazonian region played a key role! sciencedirect.com/science/articl… Follow the thread 🧵 👇

Check our new paper out today in Wiley Ecology & Evolution ! 🐢🦴📈 Fully open access here: doi.org/10.1002/ece3.7… 🧵 1/n

Tired of flattened early bird fossils? Today is your lucky day. Very happy to finally welcome 'Navaornis hestiae' to the world! It allowed us to see for the first time a (near)complete enantiornithine brain. Today in nature: nature.com/articles/s4158… #spinningskull

Thrilled to share: out now in nature (!) & just in time for US Thanksgiving, the dinosaurian history of how your turkey does the twist. Fibular reduction enabled mid-drumstick mobility, unlocking extreme knee long-axis rotation in theropods 🍗🦖🧵 nature.com/articles/s4158…

Crocodylomorphs were once far more diverse than they are today. 🐊 Fossils from Brazil’s Late Cretaceous Bauru Group include terrestrial notosuchians w/varied ecology. New analysis of Barreirosuchus franciscoi reveals semiaquatic abilities Fachini et al.: doi.org/10.1002/ar.256…

Had a great time presenting my poster at #PalAss24 today. After so many promising interactions, I couldn't be happier about my first international meeting 🥹 Congratulations to the organizing committee for such an amazing event!

It’s a wrap! The first MacroPaleo Lab field campaign, led by Professor Pedro Godoy, was a huge success! Stay tuned for more! #Paleontology #fieldwork

Back from the first fieldwork with the MacroPaleo Lab, full of learning and promising discoveries! Huge thanks to Pedro Godoy , Dr. Daniel Martins🐊 , and Luan. Lots of sweat and joy with this amazing crew! 💚🦴⚒️🦖🦴

I am delighted to announce the release of our latest paper on the evolution of giant #sloths in Science Magazine: science.org/doi/10.1126/sc… An effort that lasted years, spanned continents, and put together a team of great scientists and friends. CONICET Dialoga Exactas UBA

Ancient sloths ranged in size from tiny climbers to ground-dwelling giants. Now, researchers report in Science that this body size diversity was largely shaped by sloths’ habitats, and that these animals’ precipitous decline was likely a result of increasing human pressures.

Caçadores humanos podem ter sido os principais algozes das preguiças-gigantes. Análises evolutivas indicam que a disseminação de Homo sapiens pela América coincidiu com picos de extinção bit.ly/43dhPTf #paleontologia #biodiversidade #evolução #zoologia

Super proud of our lab students for their final course presentations: Luan Estevão dos Santos 🇧🇷🏳️‍🌈🦖 defended his MSc on elasmarian ornithischians; Kamila Lima presented a poster on her undergrad research in conservation paleobiology of freshwater turtles; and Fernanda Landim and Pedro Kenji+
