A pretty impressive tooth. I think it is an M2, 70 mm long and 37 mm across the chewing surface. Seems to be fossilized but Peace River is a dark water river and can make a modern tooth look fossilized. Would larger size imply Bison? The tooth is in fantastic shape but that can be normal for many of the fossils coming from the sand, mud, clay, gravel mixture near the banks of this spot. What about the chewing surface, it seems missing/eroded. Poor fossilization or recently erupted or ?
