2.01" Serrated Tyrannosaur Tooth - Judith River Formation

This is a fat, serrated, 2.01" long Tyrannosaur tooth from the Judith River Formation of Montana. This formation is approximately 75 million years old, or about 9 million years older than the Hell Creek Formation which also produces T. rex.

The tooth is quite thick in cross section so it would have come from near the front of the jaw. The enamel has a lot of wear, but most of the serrations are still visible.


There are three described Tyrannosaurs from the Two Medicine Formation & Judith River Formation; 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 genus because they are so similar.
