🐴🦥🐘🐪 #FossilFriday — Horse incisor & molar from Brown County
Brown County keeps delivering Ice Age finds — horse molars, mammoth tusk, and pelvis fragments from local gravels. Three New Ulm horse molars are already headed for radiocarbon dating, with more finds coming.
Lost Bones #7 is out this week and updates on Lost Bones #4 (the horse project) were previously posted:

For #FossilFriday—dinosaurs headline the Minnesota State Fair, but an Ice Age predator is also on display!
These 26,900-year-old Homotherium serum fossils from Tyson Spring Cave include a skullcap, shoulder blade and foreleg. Found beginning in 2008, they provided the first record of this scimitar-toothed cat in Minnesota and the Great Lakes region.
See them through Sept. 7!

🐂 Its a #MinnesotaMuseum #FossilFriday 🐟🐘🦥🐴🐪Today I'm spotlighting the Redwood County Museum. If you’re a naturalist — and a lover of #LostBones — this one’s for you.
The museum displays a large collection of mounted mammals and birds, along with a collection of skulls including a most wonderfully crusty bison skull. The museum also features historical and military history exhibits, a doctor’s office, and Native American artifacts.

🦌🦥🐘🐪 #FossilFriday — During and after the drainage of glacial Lake Agassiz into glacial River Warren—now the Minnesota River—river-level fluctuations, combined with the gneiss bedrock at Granite Falls, created a shifting landscape ideal for collecting sedimentary deposits and preserving bones. The Yellow Medicine County Historical Society holds a collection of bison remains from the area, some from a famous bison kill site: the Peterson Site.
