1.25" Serrated Tyrannosaur Tooth - Judith River Formation
This is a serrated, 1.25" 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 has great enamel preservation on one side and some root etchings on the reverse. Most of the serrations are present and it has minimal tip wear. One repaired crack near the tip. Comes with a small, acrylic case.

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.
