Bargain 1.35" Tyrannosaur Tooth - Two Medicine Formation

This is a nice 1.35" long Tyrannosaur tooth from the Two Medicine Formation (Judith River Group) of Eastern Montana. It has quite a bit of weathering to the surface from being exposed to the elements, but still has serrations on both edges. There are no crack repairs or restoration, but has been stabilized in a few spots to prevent breakage.

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.
