‼️New paper on Paleocene (early Danian, ~65.3 mya) decapod crustaceans from Alabama. 🙂 Eight species (incl. 2 new) is more diverse than previously known for any early Danian site in North America. Thanks also to the @paleosoc.bsky.social for grant support. Paper:

Croc Discovery Alert‼️🐊 Last month, Kelly Griffiths found an ~84 million-year-old fossil of a crocodile. It's an osteoderm or scute, a bony plate sitting primarily on the back of the animal. Found during the same @almnh.bsky.social trip for the public a hadrosaur tooth was found! 😀 #FossilFriday

Discovery Alert‼️In July, Kaylee Baize and Ava Broyles found a great piece of a mosasaur jaw in an Alabama creek during an ALMNH trip for the general public. This Cretaceous (~84 million-year-old) specimen is now in the @almnh.bsky.social paleontology collection. #FossilFriday #paleontology #fossil

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

‼️Research alert for #FossilFriday‼️ Well-preserved, ~69 million-year-old ammonites from South Dakota show two type of lethal injuries: lateral punch holes and ventral bite marks in 7.3% of the 1303 shells. Crustaceans and coleoids may be the predators. Read more: tiny.cc/wogl001 @almnh.bsky.social

#FossilFriday‼️ Tiny specimens often get overlooked, but they are important parts of ecosystems. Here's a very rare, pyritized, ~82 million-year-old coral from Harrell Station in Alabama. 😲 Collected by Jan Novak during a trip organized for the Birmingham Paleo Society. Specimen @almnh.bsky.social.

‼️Research alert for #FossilFriday. Last week, my former intern Celie Cowart presented research at UA's undergraduate conference on "Dining on Oysters during the Cretaceous Period"! While the drilling gastropod culprits did not preserve, they left their traces behind on the shells. @almnh.bsky.social

#FossilFriday‼️ Two weeks ago, I went with my Paleontology & Society class (UA's Blount Scholars Program) to Harrell Station, a classic Cretaceous site in Alabama. Everyone found various fossils, even mosasaur teeth. 😀 Here are mosa teeth found by 3 students! @almnh.bsky.social #fossil #paleontology
