Serrated, 2.26" Tyrannosaur Tooth - Judith River Formation, Montana

This is a fantastic 2.26" Tyrannosaur tooth from the Judith River Formation of Montana. This formation is approximately 70 million years old, or about 5 million years older than the Hell Creek Formation which produces T-Rex.

The tooth is in great shape with nice enamel and fine serrations. The tip of the tooth has feeding wear that continues to run up one edge of the tooth with minor chipping along this same edge. The enamel has chipped away in spots on both faces. There are also repaired cracks proximal to the roots location. Comes with a floating frame display 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.
