Tyrannosaur Dinosaur Tooth Fossil - Judith River Formation MT Albertosaurus

Description

This listing is for a Tyrannosaur tooth from the Judith River Formation of Northern MT.  The tooth is worn and is likely from an Albertosaurus or Gorgosaurus.  Pretty complete and from a juvenile young animal.
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.
