BenWorrell Posted May 5, 2018 Share Posted May 5, 2018 Hello, I'm a new member to the Fossil Forum, could someone please help me ID these teeth? I found the larger, blacker tooth this morning on a sandbar of a creek in Linn County, Iowa. My wife found the smaller tooth on the same little sandbar about a year ago. I have found several bison teeth in the many other locations I have walked up and down this river, but these two have been stumping me. These are the only teeth we have found so far that still have roots intact which leads me to believe that they did not travel very far in the creek. These may or may not be from the same animal, but two strange teeth from the same spot makes me wonder if that could be the case. The smaller one has a stylid, but even the small one is thicker than the bison teeth that I have. Two photos compare size to a modern bison jaw. Small tooth: Width: 26mm Thickness at top: 16mm Enamel height: 32mm Large tooth: Width:29mm Thickness at top: 27mm Enamel height: 14mm Link to comment Share on other sites More sharing options...

Harry Pristis Posted May 6, 2018 Share Posted May 6, 2018 I think that you've found a couple of upper bison/cow teeth, one senile with some distinctive features worn away. 5 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
BenWorrell Posted May 6, 2018 Author Share Posted May 6, 2018 @Harry Pristis Here is a photo of the larger tooth against a modern bison upper that has most comparable shape. The bison teeth I have are much smaller, is it possible it is a large ancient bison that was bigger than modern bison? Is it possible it is something else entirely? Thanks for the input! 2 Link to comment Share on other sites More sharing options...
Harry Pristis Posted May 6, 2018 Share Posted May 6, 2018 Well, it's a bovid for sure. I suspect your comparison tooth row is from a juvenile bovid with deciduous teeth. Extant Bison occidentalis is smaller than its ancestors. Identify your tooth position from the image I posted. Here are some measurements to compare: 2 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

I have this giant that has been IDed as bison, it is a biggun! 1 Link to comment Share on other sites More sharing options...
