1.14" Tyrannosaur Premax Tooth - Two Medicine Formation

This is a beautiful 1.29" long Tyrannosaur premax tooth from the Two Medicine Formation (Judith River Group) of Eastern Montana. It's in nice shape with gorgeous enamel and fine serrations on the inner edge. There is some interesting wear patterns on the outer edge near the tip where it was rubbing against another tooth in the dinosaur's mouth. There is one repaired crack in the tooth but no restoration.

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.
