Nicely Serrated 1.93" Tyrannosaur Tooth - Montana

This is a nicely serrated 1.93" 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 tooth is in excellent condition with great enamel and fine serrations. There is very little wear to the tip. There is one repaired crack near the tip with a sliver of a gap fill, but otherwise no restoration.

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.
