garyc Posted September 24, 2015 Share Posted September 24, 2015 I know it is a never ending debate around here.....the difference between bos and bison teeth. I apologize now if this bores or frustrates anyone. I think I have seen something posted before regarding crown length as an indicator; but I can't find it now. So here is a tooth I found that is quite large compared to most of my previous finds. I think it is an M3 molar and the crown measures about 48mm. Please correct me if I'm wrong. The stylid appears quite solid, with cementum in place. I'm inclined to call it bison. 1 Link to comment Share on other sites More sharing options...
ZiggieCie Posted September 24, 2015 Share Posted September 24, 2015 On your first photo, the thin ridge between the first two thicker sections is called a stylid and usually indicates a Bison. I have two of them. Here is a link that explains more. http://www.thefossilforum.com/index.php?/topic/27658-tooth-id-bison-or-cow/ Link to comment Share on other sites More sharing options...
Shellseeker Posted September 24, 2015 Share Posted September 24, 2015 Gary, I mislabeled this Gallery photo. Can not tell whether or not , this tooth is Antiquus, I just can tell that it is fossilized and 44.5 mm. http://www.thefossilforum.com/index.php?/gallery/image/37579-bison-antiquus/ And I got this from Harry on one of my previous posts. It seems to imply that you can differentiate Bos from Bison by the length of occlusal surface, but I would like Harry or RIch to confirm.

Harry Pristis Posted September 24, 2015 Share Posted September 24, 2015 (edited) Draw your own conclusions about size as a distinction between a bison m3 and a cow m3. My personal experience, ignoring other features, is that bison teeth are significantly larger. But, then, everything is bigger in Texas.

abyssunder Posted September 24, 2015 Share Posted September 24, 2015 I'm very grateful for all the pictures presented in this thread, but I have a question regarding to the occlusal view of the Bison molar. As I see, in younger age the molar is more flattened than in older age (also the lacunae) and the stylid not reach the occlusal surface. Is that correct?

I don't know that the occlusal surface is "flatter" in the more worn tooth . . . It does appear to be broader, though. The isolated stylid does not extend to the occlusal surface of the less worn tooth.

abyssunder Posted September 25, 2015 Share Posted September 25, 2015 Thank you for the response,Harry! So, the tooth in question is a young adult bison molar.

Bogue_bottom Posted November 17, 2016 Share Posted November 17, 2016 Harry and Shellseeker When you say a Bo vs. Bison are you refering to Bo's as Bovines? Shellseeker looks like we have the same tooth! Link to comment Share on other sites More sharing options...
garyc Posted November 18, 2016 Author Share Posted November 18, 2016 Bos, not "bo" is the scientific genus name given to cattle. Yes, yours looks a lot like shellseeker's. Would have belonged to a very mature beast. Welcome to the forum! Link to comment Share on other sites More sharing options...
Coy Creek Posted October 9, 2018 Share Posted October 9, 2018 Gary it seems I found a tooth identical to yours. I found 10/7/18 San Gabriel River at Tejos Park Near Georgetown Texas. I found it in the creek a few weeks after a heavy rainfall and creek had been flooded. Link to comment Share on other sites More sharing options...
garyc Posted October 11, 2018 Author Share Posted October 11, 2018 Welcome to the forum! That is certainly either cow or bison. I do see a stylid which may indicate bison. I’ve read other info that describes both bos and bison having stylids but bison’s being more robust. Try showing pics of the tooth from different angles, including the occlusal, or chewing surface. Also, see how the length of the chewing surface compares to the pics Harry provided in a previous post. Link to comment Share on other sites More sharing options...
