This is a fine example of a deer vertebra (Odocolieus sp, white-tail deer) that was recovered from the Peace River, Bone Valley Formation, Hawthorn Group, Florida. This area has rich deposits of fossils from the Miocene, Pliocene, and Pleistocene periods (approx. 11,000 to 23,000,000 years ago). This vertebra is mostly complete and has very nice coloration (probably had not been in the water long). This is a more recent specimen and is likely not a "fossil" per-se, but I have no way to determine exactly how old this is.
