Serrated, 1.49" Partial Tyrannosaur Tooth - Montana

Serrated, Partial Tyrannosaur Tooth - Montana #111005

This is a 1.49" partial Tyrannosaur tooth from the Judith River Formation 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.

Three species of tyrannosaur have been described from the Two Medicine & Judith River Formations: 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 genus because they are so similar.
