Partial 2.05" Daspletosaurus (Tyrannosaur) Tooth

This is a large, partial 2.05" long Tyrannosaur tooth from the Two Medicine Formation (Judith River Group) of Eastern Montana. It's missing the tip but has good enamel preservation. The serrations are present, though a fairly worn. This would have come from a very large tooth, probably about 3.75" inches making Daspletosaurus the most likely candidate. There are a couple of repaired cracks in the tooth.

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.
