1.17" Tyrannosaur Tooth - Judith River Formation, Montana

This is a 1.17" 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.

It has beautiful enamel preservation and fine serrations with some feeding wear to the tip. One repaired crack in the middle of the tooth. Comes with a riker mount 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.
