Coon Creek Formation

The Coon Creek Formation is a late Cretaceous deposit located in West Tennessee and Northeast Mississippi. The formation has produced fossils from the marine life of the Western Interior Seaway like Mosasaurs, Plesiosaurs, and Tennessee’s state fossil Pterotrigonia thoracica. The University of Tennessee at Martin’s Coon Creek Science Center conducts a lot of important fossil collecting and research on the Coon Creek Formation and continues to help us understand Tennessee’s past.
