#FossilFriday: The giant ground sloth Megatherium, on display at the Museo Nacional de Ciencias Naturales in Madrid, Spain.

@PJaccetturo The ostrich is anatomically incorrect. It is depicted with three toes, but ostriches only have two toes: dreamstime.com/photos-images/…

This is one of the best short films I've seen in years. Very soon, we'll stop calling it "AI film" and just call it film.

@MiloGaillard3 Stygimoloch occurs higher stratigraphically than Pachycephalosaurus, so the two are unlikely to be the same taxon: scup.com/doi/10.18261/l…

#FossilFriday We have three pachycephalosaur growth series that are uncontroversial tmk: Stegoceras validum, Prenocephale prenes, and Sphaerotholus buchholtzae. Interestingly, all three taxa seem to have pretty straightforward ontogenetic trajectories. (1/4)

#FossilFriday: Promegantereon ogygia, a sabertoothed cat from the Upper Miocene of Spain. On display at the Museo Nacional de Ciencias Naturales in Madrid.

@SteveBrusatte @nytimesbooks Congrats, Steve!!

You guys!!! Whoa!! Holy crap!! The Story of Birds is a New York Times bestseller! @nytimesbooks No. 10 nonfiction & top science book in the USA during its first week. My god, thank you all! I am the luckiest guy to have such engaged and friendly readers. ☺️☺️

#FossilFriday: The cave hyena, Crocuta crocuta spelaea, on display at the National Museum, Prague.

#FossilFriday: Allosaurus, from the Upper Jurassic of Western North America and Portugal.

#FossilFriday: the spine-necked sauropod Amargasaurus, from the Early Cretaceous of Argentina.

#FossilFriday: Brachiosaurus, from the Upper Jurassic of Africa. On display at the Museum für Naturkunde Berlin.

#FossilFriday: Enhydrocyon, a bone-crushing dog from the early Miocene of Oregon.

@TomHoltzPaleo Congrats!!

Yay!

@TomHoltzPaleo 100% agree!

See, THIS is exactly an example of something you **SHOULD NOT DO ON APRIL 1**.

#FossilFriday: Stenopterygius quadriscissus, from the Lower Jurassic of Switzerland. This ichthyosaur is known to have possessed whale-like blubber, plus a countershading color pattern (dark color on top, light color below.)

#FossilFriday: The pterosaur Tapejara wellnhoferi, from the Lower Cretaceous of Brazil.

@anthon5001 Very nice!

The Showdown: Tyrannosaurus vs Triceratops! Pretty generic really, but one I've always wanted to do - showing a massive titanic tussle, where the herd comes to the rescue & a big rexy is about to get gored!

The desserts in Belgium are truly works of art!

#Fossilfriday: The hyaenid Dinocrocuta, from the Late Miocene of Eurasia and Africa. Dinocrocuta was much larger than living hyaenas, around 200 kg (440 pounds.)

#FossilFriday: The bird-like theropod Anchiornis, from the Upper Jurassic of China. Some specimens of Anchiornis are so well preserved that traces of feather pigment remain. The body appears to have grey feathers, with a reddish-brown crest of feathers on its head.

@SteveBrusatte @TomHoltzPaleo I've got it on preorder!

Coming in two months…

#FossilFriday: Triceratops horridus, on display at the Museu Nacional de História Natural e da Ciência, Lisbon, Portugal.
