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.

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

At least they have reasoning.

“Punk: fancied resemblance of the spicule array to the spiked hairstyles associated with the punk rock movement”

“Emo: …exponents canonically bear long bangs or fringes, of which the scleritome is reminiscent, as well as studded clothing recalling the anterior valves”
nature.com Nature @nature.com · Jan 9
Two newly described mollusc species, named Punk ferox and Emo vorticaudum, indicate that early molluscs were more diverse than previously thought. The spiky, wormlike fossils were found in Herefordshire in England, and date to around 430 million years ago.

Fossils of two new worm-like aculiferan species add to the diversity of this group, showing that evolution in early aculiferans generated unusual forms comparable to other crown-group molluscs.
