Phylogeny of the longest existing gastropod clade (Pleurotomariida) reconstructed with Bayesian and parsimony methods and its implications on gastropod shell characters

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🐚

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.

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.
