For #SpinosaurSaturday here’s #Spinosaurus and #Tyrannosaurus with neck muscle reconstructions. For my research, I’m looking at how much force the two theropods generated with moving their heads and necks. Big thanks to Eden Buster for helping with the reconstructions. #dinosaurs #paleontology

Growing up in the early 1990s, the ozone hole was a big environmental problem we all learned about. The world took action and the problem is receding. See also, US air and water pollution pre-EPA. Climate change is obviously a much harder problem to solve. But we can. And we must.

Deinocheirus as depicted by James Field some time around 2000. This was the defining image of Deinocheirus for my early childhood, which is odd when I go back and realise that it isn’t especially ornithomimosaurian despite clearly trying to be. The thin lips are weird but look strangely plausible!

An unexpected "After Man" reference from the 1992's "Rand McNally Picture Atlas of Prehistoric Life." The art is by Tim Hayward, a regular contributor to palaeontology themed children's books of the 1980s and 1990s. I love the look of that rabbuck!

Cretaceous Lice: Chewing lice (which look a lot like modern lice) and nits have been found on feathers dating from the mid-Cretaceous period. Which means there's a good chance that Velociraptor was riddled with lice. #Invertebrate 🧪 - www.cell.com/current-biol... - academic.oup.com/nsr/article/...

Here’s the skull of the carnivorous basal synapsid, #Dimetrodon for this #FossilFriday. Dimetrodon lived through the Early #Permian & was a top predator on land across North America & Europe, being well-known from the red beds of Texas & Oklahoma, as well as Germany. #Palaeontology #Science 🧵 1/

Absolutely terrible. @lizrenner.bsky.social is an amazing scientist, colleague, and friend. SMFH. The attacks on our science, public lands, and PEOPLE of this country are real. We will ALL be affected. www.keloland.com/keloland-com...

Bluesky completely breaking any time I try attaching more than a single image to a post is driving me to madness. I want to post artwork so badly, I’m full of motivation and ideas for discussion and have so much art to share but I need multiple photos to do it and the app just won’t let me!

My office right now. I wanted to do a #FossilFriday post with Deanna's current prep project, but it's not finished yet (watch this space). In the meantime... this is gonna be a special piece for our exhibit. #dinosaur #dinosaurs #museum #museumlife #fossil #scicomm #tyrannosaur

Say hi to Bastetodon! This hyena-size carnivore was munching on early elephants and hippos back when cat and dog ancestors were still tiny. I’ll tell you more in my latest for NatGeo.

What's been happening at Tetrapod Zoology during February 2025? A brief thread. The month started with brief thoughts on the very weird, very FAT book Fatfoot, which is all about the 'marsupial hominoid' hypothesis. Yes, you read that right... tetzoo.com/blog/2025/2/... #TetZoo #cryptozoology

Mamenchisaurid with speculative breeding "plumage" - I'm imagining these as less fluffy & more like long, floppy spines or quills that grow during the breeding season. Directly inspired by living animals #paleoart

Saw a few good traces on a Georgia-coast field trip this past weekend with my Barrier Islands class, but the best was this on a Tybee Island coastal dune, spotted by a student: what I think was a mole cricket burrow. I'd seen similar burrows on other Georgia islands, but not on Tybee. #ichnology 🧪🦗

It’s as if Americans sanitized and derided Godzilla movies as unserious and cheap to keep people from seeing a film that brutally depicts the trauma of what our nation did to Japan, as well as the different social meanings Godzilla has carried since. Oh wait that’s exactly what happened.

I found a detailed old record of an alligator preying on a ≥500 lb feral boar. The gator was old with badly worn teeth. There's also an anecdote of a nearly 4.6 meter male gator being killed by a large feral boar. Taking down these pigs is indeed a mighty feat.
