Before we close out 2025, here is Walking with Dinosaurs thread number 4 (and a bit) – this time, The Pack, my personal favourite episode. It follows the young Albertosaurus Rose as she faces the trials and tribulations of the ancient Horseshoe Canyon– will she succeed? (1/60)

Just published today - a quick nomenclatural note on an obscure non-pterodactyloid pterosaur from the Stonesfield Slate! Thomas Huxley named it in 1859, not Hermann von Meyer
Rhamphorhynchus bucklandi Huxley, 1859 is the valid name and authority for a Jurassic pterosaur (Pterosauria, RHAMPHORHYNCHIDAE) from England, not Pterodactylus bucklandi Meyer, 1832

Hey, it's my print debut for National Geographic! This fall, I got to accompany folks from the Fort Worth Zoo on an incredible adorable mission: releasing tiny Texas horned lizards to new lives in the Hill Country.

Is the grumpy-faced Texas horned lizard adorable enough to survive?
As habitat loss and invasive predators decimate the Texas horned lizard population, researchers are banking on statewide fervor to bring them back.

Hey, fellow evolutionary biologists:
If you support trans rights, like, comment, or repost this. I want to show that transphobes like Richard Dawkins are a loud minority that does not represent our community

And that’s a follow.
Actually I do have a question if you have a sec.
Without exception the most transphobic group of scientists I’ve run into online are evolutionary biologists. Every single one of them has expressed the same opinion: transness cannot be anything other than social contagion. Why?

The name "Popular Science" doesn't mean we shift our coverage depending on public opinion. It means we cover relevant subjects that are rigorously researched, reliable, and grounded in reality.

Ninety-four percent of participants in a new study stood firm in their trans identity after five years, and "detransitioning" is rare.

Funny animal videos no longer being trustworthy just fucking sucks all around. I love the wonder of animal behavior and what it says about the experience of being alive. It's because it happened in reality that it's so fun. It's not fun if it was just made up. There's no wonder there.
