1.38" Tyrannosaur Tooth With Feeding Worn Tip - Montana

This is a 1.38" Tyrannosaur tooth from the Judith River Formation 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.

The tip of the tooth is not broken but rather it was been naturally worn down down due to feeding or rubbing against another tooth in the dinosaurs jaw. It has good enamel preservation and most of the fine serrations are present. Comes with an acrylic bubble case.

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.
