.45" Wide Tyrannosaur Tooth Fragment - Montana

This is a partial .45" Tyrannosaur tooth from the Two Medicine Formation of Pondera County, Montana. The serrations are still barely noticeable on one edge of this tooth. This formation is approximately 70 million years old, or about 5 million years older than the Hell Creek Formation which produces T-Rex material. It comes with an acrylic bubble 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.
