.95" Partial, Serrated Tyrannosaur Tooth - Judith River Formation

This is a partial, serrated, .95" 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.

There is some gap fill restoration and repair work at the proximal end of the tooth.

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.
