.62" Small Theropod Tooth (Raptor) - Montana

This is a .67" long theropod tooth from the Hell Creek Formation of South Dakota. The tooth has fine serrations and the tip shows signs of feeding wear. It's very thick in cross section so likely from near the front of the jaw. Comes in an acrylic display case.

Often these smaller Tyrannosaur teeth from the Hell Creek Formation get labeled as being Dromaeosaur (Raptor) teeth based on their size. But, there is so much debate as to the exact classifications of the small theropod dinosaurs in the Hell Creek Formation, and the teeth are so similar, I feel trying to put a species on them is almost guesswork. Some maybe juvenile Tyrannosaurs such as Nanotyrannus, or Acheroraptor (a North American cousin of the famous Velociraptor) which has become somewhat of a catch all genus for the small theropod teeth from the Hell Creek Formation.
