1.36" Partial Tyrannosaur Tooth - Judith River Formation

 
 
This is a 1.36" long, partial Tyrannosaur tooth, 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.

This is the bottom half of what would have been a very large tooth. The enamel preservation is quite nice and some of the serrations are visible.


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.
