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the 1980s as the M.S. research of D. Govoni, I've led the charge with Dave the past few years to revise and expand his unpublished thesis and ensure that this diverse gastropod fauna received the formal description it deserved.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

Just one more week (till 5 Sept) to apply for the postdoc position with me at UA Museums' Department of Museum Research and Collections. NSF-project together with Jill Leonard-Pingel, @odealab.bsky.social, and @sethf.bsky.social focused on marine ecosystems in Panama. bsky.app/profile/pale...

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

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. ⚒️ 🦑
