#WorldOctopusDay! Octopuses including Octopodoidea don't preserved well in the fossil record, but their traces (predatory drill holes) can be found in some molluscan shells. Here's a Cretaceous example from a 2021 paper in collaboration with Neil Landman. #paleontology 🐙

Octopodoidea as predators near the end of the Mesozoic Marine Revolution
Abstract. Octopodoidea are a highly versatile and diverse group of marine predators comprising > 200 species today; however, their diversity and ecology

‼️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:

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.

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.

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
