For last week’s episode of Surviving Earth, I was entrusted with doing the concept design for Saurornitholestes. Here you can see my concept design and how amazingly it was translated into a 3d model by the talented artists at MilkVFX #paleoart #sciart #SurvivingEarth

While birds and bats both developed adaptations for flight, the way they went about it is so fundamentally different it affects their possible ecological adaptation. Specifically, birds can easily shift to a walking lifestyle, bats can't. 🧪 Link: www.nature.com/articles/s41...

#temnovember2025 day 27: Rewana And now for the last round of #temnovember and we have #Rewana quadricuneata a #rhytidosteid from the early #triassic of Australia, realally cool for the lack of osification on their vertebra, leathing to them being divided on 6 diferent bones

Have you ever seen a baby gar eating? This little Spotted Gar is about a week old and has started feeding on zooplankton (in this case brine shrimp/Artemia/ aka "sea monkeys").

Happy Origin Day! Published OTD in 1859

Bucket list sloth butt selfie!! This beautiful specimen is from Anza Borrego and it has THOUSANDS of in situ osteoderms. There are only two specimens with in situ osteoderms (that I know of) in North America and I’m spending the day with this one.

Today's random piece of nostalgic palaeoart: John Gurche's Tyrannosaurus! Commissioned to accompany the Field Museum's exhibition of Sue the T.rex, this is among the definitive works of 2000s T.rex artwork. It's a moody piece that makes good use of Gurche's mastery of texture and lighting. (1/6)

Em abril a @cienciasulisboa.bsky.social e Instituto Dom Luiz estiveram no XXIII Encuentro de Jóvenes Insvestigadores en Paleontología com @lexfonseca.bsky.social que falou sobre: "Appendicular myological reconstruction of Lourinhasaurus alenquerensis (Camarasauridae, Sauropada). #dinosaurs

Just published: "A revised name and new insights into the Middle Jurassic sauropod trackways from Portugal", by Vanda Santos! The Galinha Quarry footprints have a new name: Galinhapodus gomesi. Link to paper below 👇

E por outro lado, P. Fonseca (@lexfonseca.bsky.social , @cienciasulisboa.bsky.social ), com "Appendicular myological reconstruction and functional analysis of Lourinhasaurus alenquerensis (Camarasauridae, Sauropoda)", em colaboração com Daniel Vidal (@uneduniv.bsky.social , University of Chicago)

Newest #watercolor in time for Valentines is of Khaan, two of which were discovered with slightly different tail vertebrae. Males may have had more muscles there for courtship displays. #sciart #paleoart

For #FossilFriday, here's some #paleoart of a casual afternoon in the Early Cretaceous Wealden group, with iguanodonts, tyrannosauroids, polacanthids and sauropods making a mess of a watering hole. The mashed-up muds left by these animals can be found to this day in Wealden rocks. #dinosaurs #sciart
