coyote carnassials

These are two coyote carnassials, the lower first molar or "m1". They are a right and a left. Pleistocene-Holocene of Florida.

It's easy usually to distinguish between canid upper and lower carnassial teeth. The upper carnassial (Premolar 4) in canids has three roots (or "fangs" as they are called in some books). The lower carnassial - the molar - has only two roots.
