Anatomically regionalized ecological adaptation across the bird and bat skeleton.
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. 🧪

#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
King of all the antlers.

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

A close up image of a solid layer of osteoderms from a giant ground sloth.
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.
A brown and blue-green splotched Tyrannosaurus stands triumphant over the carcass of a hadrosaur. A rich bed of ferns extends far into the distance, where the fern prairie gives way to forest. Dark clouds fill a dreary sky behind the giant carnivore.
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.

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

Welcome Baminornis! Only the second undoubted bird from the Jurassic. Joining the iconic Archaeopteryx.
But Baminornis could fly better!

A blue-skied landscape set around a watering hole in the Early Cretaceous. Three large, subtly-striped iguanodonts are emerging from the water while white flying reptiles flap past them. They approach a group of smaller iguanodont species with red-orange backs and pink-grey hides, who are drinking from the water. Seen between them is the front half of an armoured dinosaur, a polacanthid, walking by. The group of small iguanodonts stands on a churned-up mess of brown mud, the product of many heavy animals coming to drink. In the mid-foreground is a small, gold tyrannosauroid with its head tilted back to trickle water down its throat. Several small, bird-like oviraptorosaurs sneak along the water margin in the lower left. Dinosaurs of opposing size - two enormous, long-armed brachiosaurs - stand in the far distance, in front of a sparse forest.
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
Photographs of isolated fossil sauropod teeth from the Upper Jurassic of Portugal, illustrating various different morphotypes. All in labial view. Each image has a vertical 1 cm scale bar nearby. Clockwise from the top centre: two heart-shaped morphotypes (type 1, ML 1928 from Barrocalvo; type 2, ML 368 from Vale Pombas, attributed to Zby atlanticus); at bottom right, a pencil-shaped morphotype (ML 2560 from Paimogo); bottom left, two compressed chisel-shaped morphotypes (type 1, ML945 from Porto das Barcas; type 2, ML 2867 from Peralta); and finally at top right, a spatulate tooth (ML 636 from Lourinhã). All specimens are housed in the Museum of Lourinhã.
