Happy National Burrito Day, everyone! (And thanks to El Burrito in Redlands, CA for the delicious meal!) 🌯 #NationalBurritoDay

My blood pressure spiked reading this ... until I realized what time (and day) it was where The Daily Mail is published. Damn you, Daily Mail.

Today is Trans Day of Visibility. Here's a thread with suggestions & options for providing needed support!

This Saturday at WonderCon 2026! (Yep, it's me!)

This Saturday at WonderCon 2026!

It was truly a privilege to be a part of the "discovery" of a second species of Ice Age mastodon in North America. Here, my friend and colleague Alton Dooley lays out the backstory of how we found this new species right under our noses. (Pertinent publications linked in the post!) #mastodons 🧪

This Saturday at WonderCon 2026!

Great thread for all those "both parties are equally bad" and "we need a brand new direction" folks out there. If you're serious about that & not just a troll, then *now* is the best time to be organizing, promoting new candidates at all levels, generating support, etc. Yet ... nada.

Happy to be participating on this panel!

There are so many genuinely good people in vertebrate paleontology. But there are also still far too many misogynists, and bullies, and outright predators. It's so critical to shine light on this abuse and these abusers, and expunge them.

"Friends" is a beloved American sitcom that aired from 1994 to 2004, following six young adults—Rachel, Ross, Monica, Chandler, Joey, and Phoebe—living in New York City. The show explores their friendships, romances, careers, and personal growth over ten seasons.

Happy Birthday, Charles Darwin! Born on this day in 1809. (The photo is from the Natural History Museum @nhm-london.bsky.social in London, England; the festive b-day frame was found online, where it was selected ... naturally.) 🦖🧪 #DarwinDay #InternationalDarwinDay

Post a banger that's not in English.

Excellent news if true.

Nice to see this wonderful, world famous fossil site getting the support it needs to move forward with plans to renovate the campus! #RanchoLaBrea #TarPits #Pleistocene #Fossils #IceAge

Lovely warm evening (unseasonably so, even for California) - sunset approaching, dappled light in the trees ... & puffs of feathers blowing in the neighbor's yard in the light breeze. It all means one thing: our local Cooper's hawk is back w/ another dead pigeon dinner. #Wildlife #Photography

For #FossilFriday: skeleton of an American mastodon, Mammut americanum, on display at the American Museum of Natural History @amnh.org in New York City, NY, US. This is the Warren Mastodon, discovered in 1845 in Newburgh, New York - the first complete mastodon skeleton ever found in the US. 🧪

New paper discussing ontogenetic growth in Tyrannosaurus rex: "Our results suggest that the Tyrannosaurus rex species complex grew more gradually and over a longer lifespan than indicated by prior models, with a protracted period of subadult development." #Paleontology #Dinosaurs 🦖🧪

Stop scrolling and post two characters that bring you happiness.

This is obscene.

Buzz is clearly fascinated by dinosaurs! The avian kind, at least. Pigeon remains courtesy of the Cooper's hawk who hangs out in the trees in our yard & helps keep the local pigeon population down. Buzz says thank ya! #Caturday #CatsOfBluesky

So, the ICE officer "fear[ed] for his life" ... yet was never actually threatened, as his very casual sidestepping while shooting the driver, shown here, makes very plain.

"ICE officer fearing for his life" my ass.

The Western Association of Vertebrate Paleontologists meetings are a fantastic venue for researchers across the spectrum, including students and early career researchers. And the Raymond Alf Museum is a great venue with an amazing team of dedicated paleontologists. Come give a talk! 🦖🧪

Happy Solstice, everyone! #WinterSolstice2025 ❄️🌨️☃️

For #FossilFriday: a skeleton of an American mastodon on display, Natural History Museum, London, UK. This particular skeleton, originally discovered in Missouri, US in 1840, was later "augmented" with additional vertebrae and ribs & named "Missourium" to distinguish it from standard mastodons. 🧪

Coming up this morning!

Boris and Sasha keeping warm - and keeping *me* warm - through the cold winter evening. (That's southern California "cold", it's actually only in the mid 60s. But I'll take the cuddles.) #Caturday #CatsOfBluesky

#OTD in 1859, Charles Darwin published his landmark work, "On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life". Our understanding of life and living things has never been the same since. #Darwin #Evolution #OriginOfSpecies 🧪

Can't wait to see this! Looks amazing! #Dinosaurs #Fossils #Paleontology 🦖🧪

I'm home from a few weeks of travel overseas & the kitties like Boris here all seem very happy to see me ... but my sinuses are forcibly reminding me that I actually do have a minor allergy to cats. Gonna take a bit to re-acclimate. Still, let the snuggles commence! #Caturday #CatsOfBluesky

For #FossilFriday: one of the very first fossils of the American mastodon ever discovered. This specimen was found at Big Bone Lick, KY, US, in 1739 by a French military expedition, then sent back to Paris for study. On display at the Galerie de Paléontologie et d’Anatomie comparée in Paris. 🧪

The Society of Vertebrate Paleontology is looking for new members for the Communications Committee - and in this age of miscommunication and misinformation, committees like this one are more needed than ever. #2025SVP
