Bargain 1.89" Tyrannosaur Tooth - Montana

 
This is a 1.89" 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 has beautifully preserved enamel with weathering in a few areas.The tip of the tooth has been broken off and lost to time. There are no crack repairs or restoration but the jagged edge of the tooth has been stabilized to prevent further breakage.

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.
