Large Partial Tyrannosaur Tooth - Two Medicine Formation

This is a partial of a large Tyrannosaur from the Judith RIver Formation in Montana. It's 1.54" in length and would have come from a tooth between 2 1/2 - 3 inches. It has decent enamel preservation and many of the 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. Based on the size I would say Daspletosaurus is the most likely as it is the largest of the three.

I've linked to the research paper below.
