    Identification:

    Dromaeosaurs have differently-sized serrations on each carina, the ones on the distal carina being much larger and pronounced than the mesial ones. The mesial carina also has a classic twist.

    Notes:

    This tooth has feeding wear facets on both the labial and lingual sides of the tip.
