2.10" Premax Tyrannosaur Tooth - Two Medicine Formation

This is an thick 2.10" long Tyrannosaur premax tooth from the Two Medicine Formation (Judith River Group) of Eastern Montana. It has a lot of root etching on it, and there is some interesting wear patterns near the tip where it was rubbing against another tooth in the dinosaur's mouth. The serrations are mostly still present and there is no restoration or repair.

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.
