Incredibly proud to see this project hit the light of day! Begun in the 1980s as the M.S. research of D. Govoni, I've led the charge with Dave the past few years to revise and expand his unpublished thesis and ensure that this diverse gastropod fauna received the formal description it deserved. 🧵

If your work involves Big Palaeo Data, you should be *begging* people to publish little local studies of new observational data, jfc. Without that you have absolutely bupkiss. I say this as someone with a foot in both camps:

Type locality of Pecten pealeii Conrad, 1831 [=Chlamys islandica (Müller, 1776)] is the mouth of a river in Maine maybe involving an otter.
Screenshot of text that reads, "Inhabits Maine, where it was found by Mr. T. R. Peale, at the mouth of a river, having probably been brought there by an otter.

A Mother's Love Totem 🍃🦕✨💖 My piece in the upcoming Giant Robot Store Reanimated exhibition! Can you guess the inspiration? Art will be available online Saturday, July 5th at 11am PT via the GR webstore here: www.giantrobot.com #art #pottery #SciArt
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. ⚒️ 🦑

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 🦑🐌
A grey stair step structure in a case covered in marine snail shells of various sizes, shapes, and colors. My ghostly reflection haunts the narrative.

Happy #FossilFriday!! Here's MPM's "Swift-Running Rhinoceros," Trigonias osborni from the Eocene of Colorado. Looks pretty fast I guess.

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!

😲 #FossilFriday‼️ Not one but two rare, pyritized ammonites were discovered at Harrell Station during a recent trip organized for the Birmingham Paleo Society. The only two non-jaw pieces in the last 5 years! Cretaceous (~82 Ma), Alabama. Collectors: Chase Egli & Adiel Klompmaker @almnh.bsky.social
