Feeding Damage 1.11" Tyrannosaur Tooth - Montana

This is a bargain 1.11" long Tyrannosaur tooth from the Two Medicine Formation (Judith River Group) of Eastern Montana. The tip has been sheared away and appears to be due to feeding damage. The enamel on most of the tooth is decent and there is an interesting wear facet on the outer edge.

There are three described Tyrannosaurs from the Two Medicine Formation (Judith River Group), Albertosaurus, Gorgosaurus and Daspletosaurus. Research done on teeth from these three Tyrannosaurs has concluded that isolated teeth are statistically impossible to assign to a specific genre because they are so similar. I've linked to the research paper below.
