Bargain .85" Tyrannosaur Tooth Core

This is a tooth core of a small Tyrannosaur tooth from the Two Medicine Formation of Montana. The outer portion of the tooth is missing.

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.
