This striped formation may contain the oldest intact rocks on Earth.* A new study suggests that they are at least 4.16 billion years old--relics from a time before plate tectonics, probably before oceans, even. * The pocket knife is a more recent element. 🧪 www.sciencenews.org/article/eart...

Every study about vaccines that comes out is like "this vaccine is 97% effective at preventing this disease & also 3 other diseases & it somehow helps you play the violin beautifully" and antivaxxers are doing their own research that's telling them they can cure measles by eating polar bear liver.

foundationally dishonest is a pretty good summary of ai tools

Women WILL NOT STAND FOR THIS SLAVERY CRAP! The hell with that drunk idiot. His TRUMPEDUP days are numbered, because we will not forget these scum & justice will be served by WE THE PEOPLE. I hope nobody but his hand is fuking that loser in the meantime.

Fresh hell.

My latest article 👇 gets into how hard it is to date stuff in some of the oldest rocks on the planet, and why it matters ⚒️🧪 arstechnica.com/science/2025...

Happy #FossilFriday from the BEST fossil shark specimen on display anywhere (it’s at KU) This Cretoxyrhina mantelli skeleton has the bones of a big Xiphactinus audax mixed in with it, showing the shark died shortly after ingesting the absolute worst fish in the late Cretaceous seaway. 🧪🦈

What kind of AI governance do we need? Our new piece in @science.org answers this: we need policy grounded in evidence and built to generate more of it. Evidence-based policymaking is not a slogan—it’s a design challenge for democratic governance in the age of AI www.science.org/doi/10.1126/... 🧵

What do fossils tell us about evolution? Kinda a broad topic...and I tried to give it a go in 20 minutes. Using dinosaurs and mammals as my guide (sorry foram and brachiopod fans!). Check out the video here:

A beautifully preserved bothremydid turtle from the Late Cretaceous Mooreville chalk of west Ala. We collected it in the late 1990s, and it's now on display at @Mcwane w/many more wonderful fossils. (The specimen was found lying on its back plastron up.) Splendid specimen.

“What you believe is that some people have less worth than other people, and I think that is an indecent position to take. As a result, there are no details you can present within that framework that interest me in the slightest, and I don’t see any point in any debate about those details.”

The Japanese edition of my #AncientSeaReptiles has arrived, and it's great. It's a new version for 2025, so contains changes and images not yet featured in English editions. It has great design features (like the art on the cover boards). I'll be bringing a copy to #DinoConUk :)

My favorite journal, which published our description of the huge macrobaenid turtle, Appalachemys.

Unspeakably heartbreaking, as we become ever more committed to a long American Dark Age.

Unthinkable.

If you’re curious about the abridged history of how NASA ended up where it is today (amazing science agency that faltered for decades on human spaceflight), this is a really great and accurate read. 🧪

This is genuinely one of the best news of the year. Congratulations to @tetzoo.bsky.social and the PhP staff for keeping the best paleoseries alive and well. I can't even begin to express how excited I am, it looks so beautiful already! And new time period to boot! Can't wait for the first trailer!

A new pin badge design. I’ll be selling these at @dinoconuk.bsky.social next month if anybody wants one…

Cambrian aged trilobite, Modocia typicalis, from the Marjum Fm. of Utah. This one is only about 1 cm, but I have a couple waiting to be prepped that are closer to 5 cm. #TrilobiteTuesday
