Happy #FossilFriday! Why’d the Giant Beaver lose its head? Because it’s going to the Minnesota State Fair! Our actual Giant Beaver skeleton is traveling to the North End Event Center, in the Ultimate Dinosaurs exhibit, celebrating it officially becoming our State Fossil. Come see it for yourself! 🦫

#FossilFriday 3.6-billion-year-old gneiss bedrock at Granite Falls Minnesota, created a landscape ideal for collecting sediment layers and preserving bones. Yellow Medicine County Historical Society holds a collection of bison remains from the area, some from a famous bison kill: the Peterson Site.

Happy #FossilFriday! The outreach continues! Today I presented for a summer youth program hosted at Gustavus Adolphus College in Saint Peter, Minnesota. We covered lots of dinos, Ice Age beasts, the state fossil and a titanic snake. Such a great crowd!

Happy #FossilFriday! This past week the paleo team from the Science Museum of Minnesota was at TWO breweries talking science! First up was Bad Weather Brewing for their Summer Block Party then Indeed Brewing last night to do a talk & table on #dinosaurs (and other ancient life). Great times! 🦖🍻

An Eremotherium #FossilFriday. This remarkable giant ground sloth, Eremotherium laurillardi, stands at the Smithsonian’s National Museum of Natural History. Remounted on a new steel armature during the renovation of the Hall of Fossils–Deep Time in 2019, it reportedly reaches to a height of 13 feet.

Happy #FossilFriday! Check out some recent finds from fieldwork in #NorthDakota! A claw, tooth, and osteoderms (armor plates) of Borealosuchus + some turtle shell. These are all about 60 million years old from life’s recovery phase after the big extinction that ended the Age of the Dinosaurs.

🐂 🐴🐪 #FossilFriday Still one of my favorite mounts! 9K years ago, a group of Bison occidentalis wandered into what’s St, Paul MN. In 1955, at Mississippi St. & Maryland road crews found them resting beneath a peat layer. Today the remains form specimen P68.54.1 at the Science Museum of Minnesota.

The exhibit label includes the Dakota and Ojibwe names for this robust Ice Age species: Ehañna Ṭaṭanka (Dakota) Gete mashkode bizhiki (Ojibwe)Bison remains found by construction crews digging the Trout Brook sewer line—along what is now the I 35E corridor—the bones were scattered. Three bison sculls were found beautifully preserved, resting on a thin layer of marl buried in a peat deposit.

#FossilFriday specimen SMM P2025.8.6 (MNH 779) comes from Nicollet County near St. Peter, Minnesota’s almost‑capital. #11 of 12 in the state’s Ice Age horse project heading to UC Irvine’s W. M. Keck Carbon Cycle Accelerator Mass Spectrometer Facility (KCCAMS) for radiocarbon dating this summer.

Huge day for reptile evolution. We FINALLY find strong morpho-/paleontological support for Pantestudines with Archosauria. WOO! 🐢 + 🐊🦩 Eunotosaurus is firmly down on the reptile stem. "Eu-not-a-turtle" amirite?? Phylo tests ALL prior candidates for turtle origins in one deeply satisfying work.

Our paper on turtle origins is finally out in Current Biology, with two major implications for our understanding of reptile evolution 🐢 #Paleontology #Turtles #Evolution www.cell.com/current-biol...

#FossilFriday 🐘🦥🐴Happened upon a fantastic life‑sized mastodon with its juvenile at the Boonshoft Museum’s Entering the Ice Age exhibit in Dayton, OH recently. Great for paleo‑curious kids—plus a great mammal and historical exhibits as well as giant sloth and short‑faced bear replicas. boonshoft.org

Happy #FossilFriday! This week, the paleo team from the Science Museum of Minnesota was at Beaver Fest, at lovely Carleton College in Northfield, #Minnesota. It was our 3rd year there but the first with the Giant Beaver as Minnesota’s official state fossil. Such a good time!
