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the 1980s as the M.S. research of D. Govoni, I've led the charge with Dave the past few years to revise and expand his unpublished thesis and ensure that this diverse gastropod fauna received the formal description it deserved.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:

Job Alert‼️ Postdoctoral Fellow opportunity in paleontology/biology at the University of Alabama Museums:
careers.ua.edu/jobs/688232b... Aim: assess biotic interactions using mollusks from both sides of the Isthmus of Panama. Please share widely! @paleosoc.bsky.social @almnh.bsky.social
Postdoctoral Fellow opportunity. The NSF-funded project “Energetic Controls on Marine Benthic Community Structure in Space and Time”  aims to (1) evaluate how productivity affects the energetic and trophic structure of marine benthic communities on either side of the modern Isthmus of Panama, where there is now a strong contrast between the high productivity, upwelling-dominated regime of the eastern Pacific and the low-productivity, low-seasonality regime of the Caribbean (2) use this knowledge to evaluate the fossil record of Caribbean benthic ecosystems before, during, and after the uplift of the isthmus during which planktonic productivity decreased in the Caribbean and (3) relate ecosystem changes driven by productivity shifts to the well documented Caribbean extinction event ~2 Ma. This is a project in collaboration with Ohio State U, UC Berkeley, and STRI.
One key component of this project is to assess biotic interactions such as predation and possibly parasitism using fossil and modern molluscan assemblages from both sides of the Isthmus of Panama. I am recruiting a Postdoctoral Fellow with a background in paleontology and/or biology/ecology with strong quantitative skills, attention to detail and organization, and someone who can effectively supervise students. Conference support is provided. The postdoc will work with Dr. Adiel Klompmaker (aaklompmaker@ua.edu) within the University of Alabama Museums’ Department of Museum Research and Collections (https://collections.museums.ua.edu/). 
Initial appointment will be for 1 year, with renewal contingent upon funding. The deadline to apply is 5 September 2025 at 22:55 US Central Day Time. The salary will be $56,000 per year. Please upload a cover letter expressing your interest and qualifications, a CV, and contact details of at least two references. To apply and for more information see: https://careers.ua.edu/jobs/688232bd-b82e-49d3-90ea-06601c242dab

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.

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. ⚒️ 🦑

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.

Oops - my bad. The one on the upper right is labeled Hemipsalodon (also a cast; original specimen from Wyoming).
jonhendricks.bsky.social
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.

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
