Stunning 2.41" Tyrannosaur Tooth - Montana

This is a beautifully preserved 2.41" Tyrannosaurid tooth from the Two Medicine Formation (Judith River Group) 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.

This large tooth tooth has wonderful enamel preservation. The serrations on the inner edge are in great shape on the lower half of the tooth but get progressively worn as you move towards the tip. Most of the outer edge serrations are worn. Minimal feeding damage to the tip. There are several crack repairs but the only restoration is some thin gap fills in these cracks.

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. I've linked to the research paper below.
