About 120 million years ago, a pterosaur fell from the sky and died in a pond. A layer of sediment washed over it, preserving not only its skeleton, but also its stomach.

The resulting fossil is the first pterosaur ever found with a belly full of plants. #NationalFossilDay https://scim.ag/4hbaedc

Your regular reminder:

Please do not call bad-acting humans "rats." This is slander against rats.

Ever run `install.packages()` and wish it were faster, smarter, and more reliable?

The {pak} package speeds things up with parallel downloads, dependency solving, and reproducible installs.

As we're all taught, you can (usually) only directly date the age of a rock if it cooled from lava.

But here, scientists have dated dinosaur eggs, using uranium-lead ratios in the calcite. Hugely exciting, maybe groundbreaking.

My take @science.org

Scientists directly date dino eggshells for the first time
The new findings narrow age estimates for the clutch of eggs—and may help identify which species laid them

Some 241 million years ago in what is now England, a tiny, lizardlike creature had teeth well suited for snapping after insects.

Now named Agriodontosaurus helsbypetrae, this extinct reptile may be the oldest of its kind ever found. https://scim.ag/3V75MC5

Water anoles take a bubble of air down when they submerge, which they breathe like a tiny scuba tank, and now @lindseyswierk.bsky.social & co reveal that the reptiles may also be using the bubble like a gill, to breathe oxygen directly from the water

Thumbs are cool and all, but have you ever thought about how important thumbnails are? They just might have been the key to rodents' evolutionary success. That and more of the best from @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪

Jokes on you, that's his treadmill
Please enjoy 24 seconds of this naked mole rat's struggle to climb a small incline. He worked at it for probably five minutes while I was there.

Me too! 😂
Truly and without irony, I love that we live in a world where folks can spend time studying rodent thumbnails
Our paper on rodent thumbnails is out! Big team effort, powered by museum collections. Turns out, nails can reveal a lot about rodent evolution. Shoutout to Dr. Gordon Shepherd for the wild idea to study rodents thumbs!

New findings in Science suggest that rodents owe much of their evolutionary success to their thumb-nail (the first digit, D1), an adaptation that gave them dexterous hands for cracking seeds and nuts.
