Okay phew.
I mean, I'm sad that it's not a Cali Archaeocete, but glad that I wasn't clueless to such a neat find.

Where was that Eocene cetacean tooth from - not the West Coast!?

Nice! Concretions like that are so cool.

A pair of white dinosaur skeleton casts in red matrix with long curved necks. These are Khaan mckennaii, named for both the Mongolian term for ruler and for former AMNH curator Malcolm McKenna

A long low skull with recurved blade-like teeth belonging to Velociraptor, accompanied by a reconstruction of this bird like dinosaur showing a covering of feathers on its body Velociraptor mongoliensis skull DINosAuR Lived 80 million years ago | Collected at the Flaming Cliffs, 1995 Museum scientists discovered the first known Velociraptor fossil in the Gobi in 1923. These relatively small, carnivorous dinosaurs used their wickedly sharp claws and teeth to capture prey such as mammals, lizards and young dinosaurs. 3D print of Institute of Geology, Mongolia IGM 100/982 AMNH FARB 34118 ZHAO Chuang/PNSO pl

A cast specimen of a baby Protoceratops Protoceratops andrewsi DINOSAUR Lived 80 million years ago | Collected at Ukhaa Tolgod, 1997 Protoceratops were sheep-sized, plant-eating dinosaurs. This fossil is a baby-it does not yet have any fancy frills or horns on its skull. Those grew in as Protoceratops entered adulthood, when they may have been used for protection, to attract a mate or in fights for dominance. 3D print of Institute of Geology, Mongolia IGM 100/10020 AMNH FARB 34117

#FossilFriday some casts of the incredible dinosaur fossils from the Gobi Desert in the AMNH’s new ‘Dinosaurs of the Flaming Cliffs’ exhibit honoring our late curator Dr. Mark Norell, and his decades of work in the Gobi with Dr. Mike Novacek and many more.

Closer-up photo of "Teen Rex" specimen, showing the juvenile Tyrannosaurus skull (only about 2/3 of a meter long!) with a ridiculously beautiful fossil palm frond stretched out just beyond the open jaws

I got to see the incredible "Teen Rex" in Denver a few #FossilFriday s ago

Not only will this juvenile specimen be *hugely* helpful in understanding the growth of Tyrannosaurus, but that *gorgeous* palm frond might offer insight into which conditions could fossilize plants and bones side-by-side

A pair of small dinosaur tracks, with a roundish smaller track (3 cm wide) in front of a larger three-toed track (8 cm long and 8 cm wide), preserved in a gray sandstone; my left index finger is pointing to the larger track and serving as scale (about 2 cm wide).

For #FossilFriday, a pair (front foot, rear foot) of wee little ornithopod tracks in the Dakota Formation (~100 mya) at Dinosaur Ridge near Morrison, CO. Dinosaur Ridge is one of the most popular dinosaur tracksites in the U.S. (cc: @dinoridge.bsky.social, @maryanningsrevenge.bsky.social)

Montana Supreme Court Rules Its Constitution Entirely Protects Trans Citizens In Landmark Ruling The ruling will have enormous impacts for transgender residents in the state.

1. In a landmark ruling, the Montana Supreme Court has declared that the constitution, one of the most progressive in the nation, entirely protects transgender people.

The ruling is even insulated from SCOTUS decisions, due to how state constitutions work.

If it weren't so scary, it'd be hilarious that conservatives are deadset on having DEI for dumb ideologies

Last week I got the best photos of sea otters I think I'll ever get! @tetrameryx.bsky.social and I pulled into Morro Bay just before sunset, resulting in some pretty dramatic lighting! This is a sea otter nursery and every spring a bunch of mothers rest in the harbor here with their pups 🥹

Hampshire College to close permanently after fall 2026 semester Emma McCorkindale

While Hampshire’s case is in some ways unique, it is amazing to think that in a single lifetime - about 70 years - the US founded the greatest public and liberal arts college system in the world and then destroyed it, to build prisons, give tax cuts to the rich, and own the libs

Those mud rims are really impressive. Look like they were made yesterday.

It is. I really think the whale bone bird is beautiful and wish I knew more about the artifact. Coast Salish?

Dr. Win's student made an amazing find - a possible Pontolis anklebone!

The original namer of Pontolis was a Smithsonian scientist by the name of True, who had one of my favorite science portraits. Love the bowler. Mustache is also appropriate for someone who named a walrus.

Wow that's a cool find! Did Biewer figure any tarsals in the 2020 paper? I know the original is a skull taxon...

Also: let me know what the linguistic equivalent of mispelling "linguistic" is.

Exactly this, but also in the US.

Strictly economically, Universities and Colleges are some of the biggest employers, including, or especially, in Middle America™️.

Took 150 years to build up this model, killing it now for culture war points.

I mean for non-academics this is the lunguistic equivalent of getting together with 12 of your peers and being given *a* chair vs. being given *the* chair.

I saw some really beautiful forms of life in the woods today.

Humanity did that. Science did that. Publicly-funded research did that. Excellent universities did that. Diversity did that. International cooperation did that.

Artemis II is a perfect example of what we can do at our best.

Hey: USA and UK. Hey: British universities. This is what it’s like when you support science, invest in the future, build new infrastructure.

You know, you don’t just have to cut cut cut all of the time.
