.91" Tyrannosaur Tooth Tip - Montana

This is a nice .91" tip of a Tyrannosaur 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.

This tooth tip would have come from a much larger tooth. It has nice enamel preservation and fine serrations. Comes in an acrylic 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. I've linked to the research paper below.
