This is a fossil ear bone (periotic bulla) from a small cetacean species. It was recovered from a gravel bar in Florida's Peace River (DeSoto County, Bone Valley Formation). This bone likely belongs to a small, extinct, river dolphin (Pomatodelphis inaequalis) or Squalodelphinid sp. It is in excellent condition and well mineralized.
