This is a bovine or equine incisor tooth (exact species undetermined) recovered from the Peace River in Florida's Bone Valley Formation (Hawthorn Group). This area is rich in Miocene, Pliocene, and Pleistocene deposits (approx. 11,000 to 23,000,000 years ago). This well-preserved tooth has an intact root and shows very good dentition. This tooth may be somewhat recent and not a "fossil", but it is an interesting specimen nonetheless. Someone with more expertise may be able to positively identify the type and age of this tooth.
