Earliest oceanic tetrapod ecosystem reveals rapid complexification of Triassic marine communities

Large-eyed animals like owls 🦉 have a trade-off between large eyes & short optic nerves, which lowers eye mobility (to compensate they evolved swivelly necks)
But chameleons 🦎 have long, coiled optic nerves with extra slack for eye mobility, allowing them to use their famous large swivelly eyes 👀🧪🌏

Our new paper in @royalsocietypublishing.org is out now
We show that modern crocodiles evolved flatter and weaker skulls from domed ancestors to adapt to life in water, trading skull strength for streamlining 🐊

Did you know. That the meme-explosion that was the wooden model of Sacabambaspis (an Ordovician jawless fish) held at a Museum in Helsinki, was created by a pioneering Estonian fish paleontologist and palaeoartist, Elga Mark-Kurik. 🧵

I haven't posted much in a while because, probably unsurprisingly, my PhD has kept me busy! But I was just using this drawing of Wielandiella angustifolia from last year, and I realised that I've never shared a close-up showing all the details of the leaves! So anyway, enjoy! #paleobotany #paleoart

Happy #FossilFriday! It’s #GarWeek so check out these 50 million year old #gar fish from #Utah at the Science Museum of Minnesota! This genus, Lepisosteus, goes back to the Cretaceous and is still swimming today! Thanks to @bellmuseum.bsky.social & @garlab.bsky.social for hyping these cool #fish!

Happy #FossilFriday! Here's an *enormous* ichthyosaur skull from the Triassic of Nevada, USA. This one might be a new species?
I was lucky enough to see this at an awesome temporary ichthyosaur exhibit at the Nevada Museum of Art in Reno a couple months ago. Highly recommended

Chatting to friends, about how there's a mini crisis in English speaking world. Where palaeontology textbooks and popular books are dominated by male authors. While in Poland, opposite is true, and for decades women led popular palaeontological & geological educational publications.

CLUMSY MALE DINOSAURS INJURED FEMALES DURING MATING: Our new paper (Filippo Bertozzo et al. 2025), shows that a common tail injury seen in duckbilled dinosaurs was probably caused by heavy male dinosaurs clumsily crushing the spines of females during mating.
