Sharing an update because PRI shared on other socials - over $150,000 was donated this giving Tuesday bringing PRI even closer to their goal. Im very hopeful that PRI is likely to weather this crisis and create a path forward continuing its research and educational mission! Thanks all who helped!

'Tis the season for graduate school applications, so here's a reminder that I'm recruiting! My lab uses a combination of fossils, statistical phylogenetics, fieldwork, & computational methods to study macroevolutionary dynamics in the marine biosphere. Check the link below & feel free to reach out

Frog knocked at Toad’s door. “Toad, wake up,” he cried. “Come out and see how wonderful the winter is!” “I will not,” said Toad. “I am in my warm bed.”

Today I’m joining the #GivingTuesday challenge to save the Museum of the Earth. As a Board of Trustee emeritus member, I see first-hand the Museum's impact on educating our community and the world about climate change, biodiversity, and our home planet. Please donate at priweb.org/support.

Of all the wonderful depictions of Pleistocene life shown in Prehistoric Planet: Ice Age, few can compare with the beauty and realism of these psilopterines. I don't think I'm exaggerating to say this is the first and only time terror birds have been done properly in a documentary.

I was asked yesterday to post a walkthrough of Life Over Time, the shortest-lived and generally weirdest iteration of the Field Museum’s fossil halls. If you visited between 1994 and 2004, this is the version you saw. I’ve got some time, so let’s do this.

For the @nytimes.com, I wrote about Joaquinraptor, a new species from a very cool family of dinosaurs: long-armed, hook clawed (possible) tyrannosaur relatives from South America

For #NationalHummingbirdDay, 47-million-year-old Parargornis from Germany was a proto-hummingbird with short wing feathers like a modern hummingbird but a short, broad skull like their cousins, the swifts. Perhaps hummingbird ancestors started hovering before they drank nectar. 🪶🧪 (📷Mayr)

Hi all, me, @richardjbutler.bsky.social and the amazing UK-US-Moroccan team are delighted to announce that.. we have a new specimen of Spicomellus AND IT'S WAY WEIRDER AND WAY COOLER THAN WE EVER IMAGINED!!

When the asteroid struck, much of the world died. Burnt wood, bone, and ash scattered under darkened skies. Fungus spread over the decay, lives that also fed surviving ants. Ants who began to farm the fungus, inventing agriculture long before we did. I’ll tell you more at Smithsonian. #InvertFest
