Special thanks to Scott Garrett for the loan
of this specimen.
Scott said that he has tentatively
identified this specimen as a tooth
from the shark Agassizodus.

I agree on the tooth being an Agassizodus
tooth. It seems to be a bit weathered but I think
I can make out the outline of the top of the tooth.
