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!

It's a follow-up #FossilFriday
The mysterious bone fragment I posted about last year has an ID! After examination by the Science Museum of Minnesota, as suspected, the specimen has been confirmed as a mastodon tooth cusp.

A simple gravel‑bar discovery has turned into a scientific find — another reminder that Ice Age history is still hiding in plain sight across the Midwest.

If you would you have recognized it let me know.

🐴 #YearOfTheHorse #FossilFriday 🐟🐘🦥🐴🐪 Specimen SMM P2025.8.6 — originally MNH 779 in the Minnesota Historical Society collection — comes from Nicollet County near St. Peter, Minnesota.

Molar #11 of 12 in the statewide Ice Age horse project. All twelve will be heading to UC Irvine’s KCCAMS Facility for radiocarbon dating this summer.

Follow the full 12 tooth journey in Lost Bones #4 and its updates through the link in my bio.

"The three #NewSpecies belong to the extinct #kangaroo genus #Protemnodon, which were common members of #Cenozoic communities across #Australia and #NewGuinea until their #extinction in the Late #Pleistocene."
