Charlie, how did you ascertain that one tooth was from a bison? Do you have any idea whether it was a modern bison or the extinct long horn variety? Also the unknown tooth seems to have quite a bit of the enamel intact. Wouldn' t this indicate that it is considerably younger than the bison tooth? Have you run across any reference works that would help in identifying bones found in alluvial deposits of unknown age? I ask because the last time I ventured down to Caney Creek I found bones ranging from shark teeth to what seem to be very recent bones from local species. Some of the bone fragments I found were completely fossilized while others were not fossilized at all. _________________ David Campbell

Happy New Year, David.
Determining the tooth is a bison's tooth was quite quite complicated: I asked an osteologist...lol! The way I understand it, there is a small, vertical pillar between two sections on the side of a bison tooth. This distinguishes it from a cow or deer. Here's an extinct bison (Bison antiquus sp.) tooth recovered on McFadden Beach:
I asked the osteologist about the differential decay, and if that is an indicator of age. She said it's very difficult to assess the age of a tooth by the amount of decay because of many other variables. Same goes with bones. The only way to know for sure is to 14C date them, according to her. I personally think carbonate coatings, at least here locally, are a rough indicator of age. _________________ Charlie Hatchett
