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. 🧵

Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.

Ever wondered about the evolution of filter feeding in Antarctic seals?
If so, come along to my talk on Wednesday at 4pm in Hall 1.

Goo morning, monsters.
The smoke twirling from your nostrils, wafting from your speech, it’s stunning. Theater. No one appreciates the practice it took. They just assume you do because you’re monstrous. Shows what they know.

Back to the skies of the Kem Kem, we find one of the many toothed pterosaurs of the region, Siroccopteryx! This critter has somewhat modestly sized teeth compared to it's cousins, and I've illustrated it here with a speculative crest.

The best advice I received back when I gave my first presentation was, "This is your study and you know this subject better than anyone else who might be listening. Relax." It helped. #2025SVP
Many of our student attendees will be giving their first talk or poster this meeting! What advice you give them to help make it the best experience possible?
