Type locality of Pecten pealeii Conrad, 1831 [=Chlamys islandica (Mรผller, 1776)] is the mouth of a river in Maine maybe involving an otter.

Marvelous Mollusks โ€” Museum of the Earth Now Open!

The Online Version of the Marvelous Mollusks exhibit I helped with is now live!
I expect more photos will be added in the next few weeks of the 400+ modern and fossil specimens on exhibit!

A sgraffito ceramic sculpture done with black and orange underglazes, gold gilding, and my signature California poppies motif. The sculpture is that of a sauropod dinosaur that has a smaller sauropod on it's back. The larger sauropod's neck is craned towards the smaller one as though they're about to boop noses.

This is a fun multi institution project looking at recent past environmental change that caused extinction to predict responses to modern climate change in the marine realm. Modern and fossil colab. I was Jon's prior postdoc on the same project and would be happy to answer questions in DM. โš’๏ธ ๐Ÿฆ‘

It's finally out! 200 years since the description of Eurypterus remipes, the first eurypterid named in the scientific literature, I present a summary of the history of eurypterid research and an updated taxonomy of every known species.๐Ÿงชโš’๏ธ

Happy #molluskMonday! A display from our new exhibit at the Museum of the Earth in #Ithaca. This case is meant to show how diverse marine #snails are, with predatory species on this side, and other ecologies on the other. 82 snails in this case, >500 mollusc specimens on exhibit #Invertebrates ๐Ÿฆ‘๐ŸŒ

The label says "Hoplophoneus oreodontis," but I'm not sure if that name is current. The specimen is a cast of a specimen from Nebraska.

What's up #InverteFest, I've been embroidering a mollusc alphabet on and off since 2018, and I haven't shared them on bsky yet, so here we go - A is for Argonauta, Aporrhais, Aplysia and Architeuthis!
