Any Pleistocene Experts Out There?

Recommended Posts

Here is something that has been driving me crazy for a couple of years now. This mandible, unfortunately without any teeth, was found in a Pleistocene formation in S.C. dated at 450,000 yrs. The formation correlates most closely with the Coleman 2A site at the Leisey Shell pit in Florida. This is the only photo I have on hand right now, and it is admittedly of poor quality. Luckily I put a nickel next to it for scale. As you can see, this mandible is very narrow with very square alveoli. The wall of bone between the teeth (or roots) is very thin, and the outer wall of each alveolus is very thin. When viewed from the side, the sides of the mandible bulge outward noticeably where the teeth are. The bottom edge of the mandible comes to a fairly thin edge similar to that of a white tail deer. As you can see, this mandible if very short and thin overall. It appears to be roughly the size of a possum or racoon, but I know these are not correct. I just can't think of any species that would have such perfectly square roots or crowns. Anyone have any ideas?

It could be Bambi. Better images will help with the ID.

Coleman 2A is totally unrelated geographically to Leisey Shell Pit; they are 60 or so miles apart.
