    Description

    This listing is for a large rare Ceratopsian dinosaur tooth from the Judith River Formation of Valley County in Northern MT.
    The tooth has great detail and is a spit tooth which fell out of the dinosaur's mouth during life and feeding.  There is still some sediment on the tooth which could be easily worked off with a dental tool or xacto knife.
    There are a host of different Ceratopsians described from this formation, so it is hard to say which it is from.  There is a list below of possibilities.
    Comes with its own gem display case and COA upon request!
    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.
