Happy International Women's Day 💐 Did you know, for every 7 men in palaeontology, there are ~3 women. Women make up 25-35% of global vertebrate palaeontological publishing output. And are most likely to study mammals, while men, reptiles.

This is really interesting. There is evidence for strong natural selection on titin (striated muscle elastic component) in snakes and other Squamata/Toxicofera -- especially in wide-gaped snakes. Which makes sense biomechanically. link.springer.com/article/10.1...

Please enjoy the single most amazing quote from a paleontologist I have ever read: “The animal literally cemented itself—and its nether regions—into eternal history like the movie stars on the Hollywood Walk of Fame.” 🧪 www.scientificamerican.com/article/see-...

rewriting a more realistic script for The Lord of the Rings. Frodo just stays home and we watch thirteen hours of him cooking meals and reading books. every hour or so he glances at a newspaper and goes, "Oh shit what's happening in Rohan? That's fucked." Then he goes to the pub to drink with Sam.

They’re stealing from us. They are stealing from us and we have to put a stop to this. This cannot stand.

NCAR is foundational scientific infrastructure. This is escalating the assault on climate science, and there is a direct line between this step and the loss of many human lives.

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Here’s the thing, emerging scientists aren’t going to flee to do science elsewhere…they just won’t do the science. We will lose at least one, if not two generations of knowledge if we don’t get this shit sorted out immediately.

Presented here is this year’s entire See Jurassic Right Back To School series where I chat with TWELVE scientists and science communicators about all the cool shit they do and all their freaky, fun, and fascinating hyperfixations you need to know about, right now: podcasts.apple.com/us/podcast/t...

It’s Antarctica Day! Give it up for this articulated skeleton of Thrinaxodon, an early mammal relative from 250 million years ago, found in the Transantarctic Mountains 8 years ago. This continent has an amazing fossil heritage that we’re continuing to learn more about!

In an era marked by rapid climate change and biodiversity loss, it is imperative that we continue to invest in the unique value of natural history collections data "Global sampling decline erodes science potential of natural history collections" 🧪

GenAI has polluted image search results, especially for animal pics. It’s now basically impossible to find accurate art references. Enter this: a repository of open-access, AI-free images of wild & exotic taxa. Artists creating *without AI* have blanket permission for derivative/transformative use.

New paper alert! (My first!) This is a benchmark paper on all NPS fossils within the State of Utah through 2024. Loads of illustrations by me and pic by coauthors and collaborators. Open access, free to download! Thanks to all who made this possible! giw.utahgeology.org/giw/index.ph...

New paper alert!! Thanks to @tuttran.bsky.social for putting us all together for his first publication! It will be helpful to have much of this data in one place. Check it out: giw.utahgeology.org/giw/index.ph... #NPSpaleo

I’ve released a tool to sketch and edit phylogenetic trees! yawak.jp/PhyloWeaver/ Load a Newick file and intuitively add/remove/resize branches. Useful for quick conceptual trees, extracting subtrees, or turning ideas into Newick.

This is a "reindeer cyclone", a defensive behavior that has been observed in herds of reindeer, even in captivity. The fawns and older animals are at the center, the strongest animal in the outer lanes. The point is to confuse the brains of predators accustomed to stalking a single outlier.

My latest for @nytimes.com! For 40 years, paleontologists have grappled over whether a small tyrannosaur — named Nanotyrannus — was its own animal, or simply a teenage T.rex. The debate has been ... contentious. Which is why it's so fun to finally be able to say this: Folks? Nanotyrannus is real.

Thinking back to the spring with the cutest little Tylosaurus skull I've seen in the past few years. Just look at that stubby little rostrum (no shade, he's trying his best) Based on strat location in the Niobrara, it's probably a juvenile T. kansasensis. Can't wait to see this one get prepped 🧪

Excited to share our new paper where we find that the rise, decline and fall of clades is not explained by the usual suspects (diversity-dependence, ecological opportunities) but rather by species' insidious loss of macroevolutionary fitness: www.nature.com/articles/s41... 1/3

🦎THREAD: We just published something wild in @asn-amnat.bsky.social - lizards missing entire limbs not only survive, but some appear to actually thrive in the wild?! Let me tell you about the "three-legged pirate" lizards 🏴‍☠️ [Paper: www.journals.uchicago.edu/doi/10.1086/... ] (1/n)

Out now in Biology Letters, my latest paper tackles an apparently simple question: how many characters are needed to reconstruct a phylogeny? TL;DR: in most cases between 100 and 500, more than a substantial portion of morphological datasets, but the story is more complex... doi.org/10.1098/rsbl...

Devon knows how they made it so teeny: the fossil of a very small rhynchocephalian from the Triassic of Devon, UK, is the oldest known lepidosaur and sheds light on the early history of this important and species-rich tetrapod group. @nature.com www.nature.com/articles/s41...

Love how being sprawling-legged ectotherms does absolutely nothing to stop lizards from sometimes doing this:

Some 40 million years ago, northern Europe was covered by what is known as the Baltic Amber Forest, now known only from pieces of amber found on the coastline.
