Tyrannosaur Dinosaur Tooth Fossil - Judith River Formation MT Albertosaurus

Description

This listing is for a partial Tyrannosaur tooth from the Judith River Formation of Northern MT.  The tooth is in great condition but partial and is likely from an Albertosaurus or Gorgosaurus.
The Judith River Formation dates back to the Late Cretaceous approximately 75 million years in age. It represent the coastline of an ancient sea that spanned across the middle of North American during much of the Mesozoic Era. That is why dinosaur remains are so common in the American West, those areas were the ancient floodplains of a seaway that no longer exists.
