Here are some fossil pleurotomariids, which have lived in Earth’s oceans for over 450 million years.This is a kind of snail you won’t find in your garden or on a seashore. You’d have to dive 400 meters to see a living one.If you could beachcomb in the Jurassic, you’d probably find one on the coast🐚

Snails 🐌 ! a 🧵 of snail pics on my phone as a snail paleontologist.

Turritella cooperi

Excluded: videos, John Oliver save PRI posts, pics of snails with lots od not snails.
BTW, donating to PRI is definitely in the realm of "save the snails", lots of snail history there, 1 mil+ 🐌specimens

Some snails from work: Cross-sectioned pleurotomarioid, cross-sectioned Campanile, truly behemoth cowry, and ( just casually) the type of Ecphora quadricostata (Say)

Fossilized masses of little tiny egg-shaped poops keep showing up in surprising places - inside fish braincases, inside pulp cavities of whale and dolphin teeth, and now, within the middle ear sinus of an extinct dolphin. Who, uh, dealt these? coastalpaleo.blogspot.com/2025/11/acid...

Lingulids have seen perhaps the coldest, slowest taxonomic debates you can imagine over the past few decades. While there was a general sense that most Paleozoic and Mesozoic taxa weren't actually Lingula, early attempts at revision were ... problematic.

A dumb question for taxonomic friends: who came up with the idea for type specimens? Everything I read defines things like holotypes, but doesn't explain where the bigger concept first came from. @americanbeetles.bsky.social @alexwild.bsky.social @morethanadodo.bsky.social

This #fossilfriday, we move in time to the #Permian when the #amphibian Seymouria sanjuanensis lived in what is New Mexico today. Clusters of large animals like this one are rarely found in the #fossil record, especially this well preserved.

An analysis of over 5,000 fossils found dung beetles developed a taste for fetid meat significantly earlier than previously believed.

The 37-million-year-old discovery suggests fierce fecal competition drove some species to start eating flesh.

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...

A 126,000-year-old butt-drag just made fossil history.
A tiny rock hyrax scooted across the sand of ancient South Africa, and that moment was preserved in stone.
