Odd Shaped, .74" Tyrannosaur Premax Tooth - Montana

This is a oddly shaped, .74" Tyrannosaur tooth from the Judith River Formation of Montana. This Formation is about 5 million years older than the Hell Creek Formation where T-Rex comes from.

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. This means the best we can do on identification is this is a premax tooth of one of these Tyrannosaurs. I've linked to the research paper below.
