Serrated, 1.6" Tyrannosaur Tooth in Rock - Judith River Formation

This is a very nice 1.6" Tyrannosaur tooth that has been almost entirely exposed from the rock it was found in, from the Judith River Formation of Montana. The rock has been stabilized with glue.

The serrations are present along both edges, with some minor chipping in points of breakage through the tooth. These points of breakage consist of a repaired crack at the tip and a repaired crack at the middle of the tooth. The enamel is in good condition for the most part, though there is some weathering to one face, along with what looks like scratching to the same face.

There are three described Tyrannosaurs from the Two Medicine Formation & Judith River Formation, 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.
