MatthewS.Paleofan Posted February 23, 2017 Share Posted February 23, 2017 Does anyone know when Bison died out in Iowa? I myself have a single vertebrae and the front lower left half of a buffalo jaw with 2 teeth in it. I think it must be any wear from 500-to a couple thousand years as it is dark brown in color. 16 - 1.webp Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 23, 2017 Share Posted February 23, 2017 Color is not a great data point for age. Some rivers are very rich in tannins, which can color bone very quickly.

Well I did have to assume, the man who gave it to me is a friend of my dads, he said that he was an avid fossil hunter...Than when he gave me the vertebrae, he said it belonged to a mammoth.. I had to search for myself to find it was a Bisons. So It may be from the 1880s, who knows. Link to comment Share on other sites More sharing options...
