Winding down #Caturday

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

More exciting hominin remains from 2.9-2.5 million year old deposits in northern Ethiopia! 🧪 #Paleoanthropology #Paleontology

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. 🧪

For all your Tyrannosaurus & Nanotyrannus needs! 🦖🧪

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.

Tigger has discovered a shopping bag. #Caturday #CatsOfBluesky

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! 🦖🧪

Me heading into 2026. #NewYears

Celebrating the holidays Riverside-style. #HappyHolidays #FestivalOfLights

You will be visited by three spirits ...

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

The best advice I received back when I gave my first presentation was, "This is your study and you know this subject better than anyone else who might be listening. Relax." It helped. #2025SVP

Pomegranates in our yard. #LazySunday

This is Sasha. She is my heart. #Caturday #CatsOfBluesky

Fascinating new study from @arctomet.bsky.social about how differences in parental care (or lack thereof) between Mesozoic dinosaurs and Cenozoic mammals might potentially affect interpretations of species diversity and trophic abundance in ancient communities. 🦖🧪

I didn't know that today was National Sandwich Day when I made this grilled cheese, but what the heck, it'll do. #NationalSandwichDay 🥪

The Museum of the Rockies @museumoftherockies.bsky.social is one of the premier paleontology museums in the western US, routinely producing cutting-edge science and showcasing some truly spectacular fossils. Please consider giving them a follow! 🦖🧪

Movies in a darkened room on Halloween night: "Cabin in the Woods", "Tucker and Dale vs. Evil", and "The Frighteners". Plus margaritas. 🎃 #HappyHalloween

Happy National Cat Day to all who celebrate from (clockwise from top left) Arya, Buzz, Tigger, Zorro, Boris, and Sasha! (Arya is perched on my back while Sasha is lounging in my lap in this collage, in case you were wondering.) #NationalCatDay #CatsOfBluesky

The Society of Vertebrate Paleontology (SVP) @societyofvertpaleo.bsky.social has just published their "Best Practice Guidelines for Mitigation of Adverse Impacts on Paleontological Resources" for paleontologists around the world who work to recover & conserve fossils threatened by human activities.

Jeebus, this game. #Dodgers

Boris is keeping an eye out for anything that might be happening today on #NationalBlackCatDay ... but so far, nothing much going on. Oh, well, Halloween is in the offing ... #CatsOfBluesky

Last minute #FossilFriday entry: a fossil onyx slippersnail, Crepidula onyx, from Pliocene deposits in Ventura Co. CA, found on a construction site by my paleontologist wife Kim & currently on display @ the Western Science Center in Hemet, CA as part of their new "Life in the Slow Lane" exhibit! 🧪🐌

More fossil ground sloths for #InternationalSlothDay!

Happy #InternationalSlothDay! To celebrate w/ a paleontology twist, here's a fossilized skull and lower jaw of the extinct Pleistocene (Ice Age) ground sloth Paramylodon harlani, discovered in 2018 during excavation for the LA subway's La Cienega Station. 🧪🦥 #WorldSlothDay #MylodontMonday
