2.2" Serrated, Tyrannosaur Tooth - Judith River Formation

This is a 2.2" long Tyrannosaur tooth on stone, from the Judith River Formation of Montana. This formation is approximately 75 million years old, or about 9 million years older than the Hell Creek Formation which also produces T. rex. There is a repaired crack through the middle of the tooth, with restoration between the two halves that broke apart. The tip of the tooth has undergone heavy feeding wear and aside from a small section of serrations, the majority have worn away. There is a repaired crack at the proximal end of the tooth.

Comes with a floating frame display case.

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.
