Gorgeous 1.28" Tyrannosaur Tooth - Fine Serrations

This is a gorgeous 1.28" 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. T

he preservation on this tooth is stunning, with nearly flawless black enamel. This black enamel coloration is FAR more rare than the teeth with brown enamel. The fine serrations on both edges are well preserved and there is minimal feeding damage to the tip. There is one repaired crack, but no restoration. Really a nice, high quality tooth.

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.
