Serrated, .66" Tyrannosaur Tooth - Judith River Formation

This is a pristine, .66" long, serrated, Tyrannosaur tooth tip, 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.

It would have almost certainly come from a juvenile animal. Very nice preservation.

Three species of tyrannosaur have been described from the Two Medicine & Judith River Formations: 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.
