1.62" Partial Tyrannosaur Tooth - Montana

This is a partial,1.62" 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 is a section of a pretty good sized tooth, probably over 3 inches in length. It's missing the tip and there is a pretty good size gap in the middle where the recovered pieces were put back together. Some of the serrations are still visible.

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.
