#FossilFriday 🦂 UMMNH has a new exhibit on eurypterids! I’m providing some work-in-progress research on eurypterid feeding behavior.

#FossilFriday Stunning fossil shows dinosaurs’ distinctive path to flight www.nature.com/articles/d41...

Happy #FossilFriday! Had an amazing week taking part in BeaverCON in Minneapolis this year! I presented on the Giant Beaver as our state fossil and learned SO much 🦫! We even brought a bunch of #beaver fossils from the Science Museum of Minnesota to the @bellmuseum.bsky.social for a Dam Good Night!

Breaking my silence this #FossilFriday to confirm that I'm a madman doing back-to-back conferences next month.

Also, stay tuned for another big (for me) announcement later this month...

A colorful flyer for IPC7 with a primarily black background bordered by alternating red, blue, green, yellow, and orange blocks. Each block along the bottom has line drawings of paleontological or geological features of South Africa, including Table Mountain and a Lystrosaurus skull.

Happy #FossilFriday from this basic as all hell Tyrannosaurus rex tooth!

Another cool find for #FossilFriday: 66 Mya, a theropod dinosaur munched on a toothed diving bird, and we know it because its feathers were preserved in the dino's 💩

#PaleoSky ⚒️🧪🦕

While some dinosaurs are thought to have had ‘fuzzy’ or ‘downy’ feathers (shown in this illustration as the yellow spikes on a Nanotyrannus’ neck), ancient birds (such as the one in the Nanotyrannus’ mouth) were more likely to have had feathers that look similar to the birds of today.

Welcome to #gomphtober2026 . Kicking things off is the lower jaw of Torynobelodon, a shovel-tusker found in Cherry County, Nebraska. On diaplay at the University of Nebraska State Museum, Lincoln.

#FossilFriday brings canoodling Seymouria, a largely terrestrial Permian tetrapod thought to be a stem amphibian.

This replica is from our collection, but the original is apparently at Carnegie. They're called the Tambach lovers, although Seymouria aggregations have been found elsewhere too. 🧪⚒️

Replica cast of two canoodling Seymouria sanjuanensis, early Permian, Germany.

Huh, didn’t notice the donor until just now. Guess the original's at Carnegie!

It's #fossilfriday! Meet Hatzegopteryx, a predatory, ground-stalking pterosaur the size of a small giraffe, found on the islands of Cretaceous Eastern Europe.

Survival Verdict: lol good luck

HOW TO SURVIVE PREHISTORY. Out April 27, 2027. Preorder now! bookshop.org/p/books/how-...

An enormous Hatzegopteryx pterosaur stands in the rain on all fours, its head a mass of turkey-like wrinkles around a wicked, machete-shaped beak. It turns a cold, considering eye on you. Two others approach through the mist. Art by Stieven Van Der Poorten for HOW TO SURVIVE PREHISTORY

#fossilfriday The fossil mastodon molar found in a streambed in the Santa Cruz Mountains a month ago or so, recently donated to a research collection at Stanford. Photo by Jeff Chiu. 🦖🧪

A photo of a well-preserved mastodon tooth in an archival box; it has five transverse ridges or lophs, with gray enamel, and a series of reddish banana-shaped roots.

Did dinosaurs evolve flight more than once?

Maybe! Not only birds, but microraptors too…

I unpack it for @newscientist.com with @rowhoop.bsky.social & @pennysarchet.bsky.social #fossilfriday

Here's a freshly-found Gastonia osteoderm (with a visually helpful plastic Gastonia model) for #FossilFriday out here at Lorrie's Site in eastern Utah.

This is the world's largest and most prolific ankylosaur bonebed, with all the specimens we're excavating going to @prehistoricmuseum.bsky.social

I haven't posted anything for a while, so here's some new #paleoart for #FossilFriday: Cetiosaurus in a Middle Jurassic landscape. I've had to compose and execute this in just two days, so hopefully it looks OK! (All data for the plant recons comes from @palaeojules.bsky.social.)

#fossilfriday los pequeñines también tienen su encanto.

Un dedo señalando un fósil de ammonite del tamaño de la uña, está en el suelo, en el campo, rodeado de otros fósiles de braquiópodos y fragmentos calizos.
