Hi, does anyone have an idea what museum might have had labels like the one on this specimen. We're trying to return a bunch of old loans, and this specimen has no information. It's a receptaculite, maybe that helps.

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

We are therefore especially motivated to have researchers from different backgrounds from across all aspects of paleobiology present during this session, such that an integrated examination of the imaging frontier of paleobiology can be explored.

This is especially important as researchers from different parts of paleobiology seldom find themselves in the same sessions.

This will present an important opportunity to bring this distinguished group of thinkers together, and allow researchers across these fields to interact, developing connections that would likely not otherwise be possible.

This session aims to span topics in vertebrate, invertebrate, botanical, and trace fossil research and examine how imaging methods can be used to understand these sub-fields, producing a unique, cross-disciplinary environment.
