RE: Bones and Stomach acid
When finding teeth lacking enamel, it is important that exfoliation of the
enamel due to freeze-thaw cycles (created while the bone was laying on the
surface of the ground), be first ruled out. Freeze-thaw cycles do an excellent
job of removing tooth enamel from the dentine of a fossil, and many an
exfoliated tooth has been mis-identified as a tooth that passed through a
critter's digestive tract.

Check out this citation for more info. It's a pretty cool paper.

Sorry if someone else has already posted this. I get the mailing list as a
