Invertebrate Paleontology - Sam Noble Museum
With nearly one million specimens from every major invertebrate fossil group, the invertebrate paleontology collection is among the most scientifically important in North America. It contains nearly 3,000 primary type specimens and about 7,000 figured specimens. The majority of samples in the collection include detailed ancillary information on geographic and stratigraphic occurrence. The collection represents

Many thanks to @astigall.bsky.social for coming to OU last week to give an awesome colloquium talk & visit the Sam Noble Museum! It was a semester highlight for us in @oupaleobiology.bsky.social and (as always) it was super great to catch up and chat science with one of my favorite paleontologists!

Check it out if you're interested in modeling morphological evolution, its impact on fossil phylogenies, and the macroevolutionary inferences derived from them. There's a bit of a cautionary(?) tale about continuous characters in here, too. Can't believe they let me quote Vonnegut's Sirens of Titan!

As a paleontologist, here's something incredible about the geosciences program at OU:

1. Overall freshmen enrollment has been * increasing * in recent years.
2. We have more students in our * Paleobiology * Bachelor of Science program than any other option (including the general geosciences path)

Very proud of @oupaleobiology.bsky.social graduate students @crowleyk.bsky.social & Alysha Zazubec for their contributions to the 2025 field season on Anticosti Island. I'm particularly excited about the fantastic echinoderm fossils they found this year!
Another day in the field with the Sam Noble Oklahoma Museum of Natural History team on Anticosti Island. Here, Lena and I are joined by OU Geosciences grad students Kiera Crowley (Wright lab) and Alysha Zazubec (Cole lab)

New paper for #FossilFriday by Sam Noble Museum / OU paleontologists Lena Cole and Davey Wright, with AMNH collaborator Melanie Hopkins. Check it out!
New paper! The 1st publication from our NSF grant investigating local to global biodiversity patterns in marine invertebrates across the O-S boundary is out! Here, we describe a new crinoid from Anticosti Island & use Bayesian tip-dating approaches to quantify uncertainty in its stratigraphic age 🧪

Flexible crinoids are really cool group of rare & morphologically distinct fossil echinoderms. They originated during the Ordovician but substantially increase in diversity, disparity, & abundance in the Silurian after the mass extinction, so a new taxon near the boundary is a significant discovery.

I'll have more info in a few weeks when I get back from fieldwork but I'll be recruiting 2 graduate students to begin in 2026 (1 PhD, 1 MS). My lab investigates macroevolutionary dynamics using phylogenetic methods & the fossil record. Please share with students having strong research interests!

TFW you're about to leave for fieldwork so you create t-shirts for the team of researchers, staff, and students. This year's intrepid, multi-institutional team involves folks from the Sam Noble Oklahoma Museum of Natural History & the American Museum of Natural History. Does anyone else do this? 🧪
