Bargain 1.87" Tyrannosaur Tooth - Two Medicine Formation

This is a bargain 1.87" long Tyrannosaur tooth from the Two Medicine Formation (Judith River Group) of Eastern Montana. All the enamel has been worn away from the exterior and it had to be put back together from many pieces. Some of the inner serrations are still visible.

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.
