.82" Serrated, Juvenile Tyrannosaur Tooth - Montana

This is a serrated, .82" 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.

A tooth of this size almost certainly would have come from a juvenile. Nice serrations and and a tip with almost no wear. One repaired crack near the tip. Comes in an acrylic display case.

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.
