1.51" Tyrannosaur Tooth - Montana

This is a 1.51" Tyrannosaurid tooth from the Two Medicine Formation (Judith River Group) of Montana. This formation is approximately 70 million years old, or about 5 million years old than the Hell Creek Formation which produces T-Rex.

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.

The tooth has some bleaching from exposure to the sun and root etching to the surface. The anterior serrations are in good shape and it has no restoration or repair.
