Robust, 2.15" Tyrannosaur Tooth - Montana

This is a robust 2.15" 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.

This is a pretty good size tooth and given the thick cross-section is likely a premax tooth from the front of the jaw. The tooth is pretty well worn with most of the enamel missing. Comes with a floating frame 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.
