This is a lot of two (2) fossil bones that were recovered from the Peace River in the Bone Valley formation of Florida (Miocene Period, approx. 7-14 million years old). I cannot positively identify what animal species these bones originate from because they are too worn. Both bones have straight gouges or cuts that were made by a predator when the animal was killed, or shortly after by scavengers. It is not often you get to see evidence of what killed the animal before it became fossilized. Each bone is approximately 3 inches long. One of the bones is hollow. The other bone has a tiny shark tooth lodged on the inside - not related to the predatory marks, but a nice bonus in any case.
