1.56" Serrated Tyrannosaur Tooth in Situ - Judith River Formation

This is a serrated, 1.56" 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.

It comes with an acrylic display stand.

Three species of tyrannosaur have been described from the Two Medicine & Judith River Formations: 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.
