#fossilfriday 🐱☠️ Sabretooth cats roamed the Midwest! Information released by Iowa State University describes a sub-adult male Smilodon fatalis skull found on the East Ninshnabotna River near Shenandoah Iowa.

Researchers used radiocarbon dating to age the Iowa cat to ~13,500 years. The find adds to a total of only about 70 specimens found across the country (other than La Brea) and a 1st in Iowa.

It’s #Minnesota #MammalMonday! 🐴🐪🦣🦥🍃 You could say horses made America – feeding the American big cats during the Pleistocene and then propelling humans into the modern age.

This decrepit skull from Bannack, Montana, and butchered tibia found in New Ulm, Minnesota highlight both the modern mystique and the utility of the horse. 🐎

Happy #Minnesota #FossilFriday! 🦬🐪🦣🦥🦫🍃 What is the most common Bison bison specimen found in river gravels besides teeth in Southern Minnesota? It's usually a metacarpal or a metatarsal.

These stout solid bones survive well within a river's fluvial processes. Here are a few example specimens.🦴

Happy #Minnesota #FossilFriday! 🦬🍃🦣🐪🦥 Here is a beefy Bison bison humerus found last fall by a friend of mine in Southern Minnesota. It was found eroding out of the side of a small tributary about 4 feet below the soil surface – just downhill from a tee box on a local golf course. ⛳

It has since been donated to the Science Museum of Minnesota for further study.

It's #Minnesota #MammothMonday. 🦣🦷 More Southern Minnesota proboscideans! - see my previous #MammothMonday posts. Here's a partial tooth found in 2019 by a friend. It was stuck in the muddy river bottom along a cut bank. Surprisingly not fully tumbled apart - the rest of the animal could be close! Donated to the #sciencemuseumofmn. 🦣🦥🐴🐪🦬🍃

Happy #Minnesota #FossilFriday. 🦬🍃🦣🦥🐴🐪 More Bison bison. I found this 47cm bison femur partially buried in a riverbed in Southern Minnesota. It has been donated to the Science Museum of Minnesota for further research. See my previous #fossilfriday posts and the Specimen Spotlight video below for more. 🦬

It's #Minnesota #MammothMonday. 🦣🦥🐴🐪🦬🍃 More Southern Minnesota mammoths! - see my previous #MammothMonday posts. Here's a fragment of a tusk found in 2019 on a river gravel bar. It is the "outer bark" - not dentine or ivory but cementum. Now, where is the rest of the animal!?

#SeptarianSunday! 💎 🦣🦥 Sometimes when out fossil hunting I also come across the occasional sedimentary anomaly. This septarian nodule was found along the Crow River in central Minnesota on a gravel bar. It is very loosely formed but I ‘dig’ it! 🦬🍂🦫

🐴 Happy #Minnesota #FossilFriday! The next year of the horse isn't until 2026 but the last couple of years have uncovered many horse specimens for me and a fellow fossil hunter. Horse specimens for us are second only to Bison bison finds. One of these teeth, if verified, will be the first Pleistocene horse documented in Minnesota!
