Serrated, 1.47" Tyrannosaur Tooth - Judith River Formation, Montana

This is a 1.47" 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.

Fine enamel preservation and serrations along both edges of this tooth. There are two repaired cracks near the tip of this tooth. 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.
