1.39" Serrated, Tyrannosaur Tooth - Judith River Formation

This is a 1.39" 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 are two merging repaired cracks through the tooth about a half an inch away from the tip, with a .29 x .12" section of restoration between the repaired cracks, as well as some small spots of chipping to the serrations. Otherwise, the tooth is in great conditions with overall fine serrations.

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 genus because they are so similar.
