1 week, 2 days ago Laurel Badura posted an image in the group What is it? from the myFOSSIL app I believe the top two rows are bison teeth. The bottom two teeth…are those bison as well or something else? Found on the Platte River Jeanette Pirlo replied 2 days, 1 hour ago The bottom row look like horse incisors. The middle row may be horse or bison fragments.
