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. Dinosaur like the famous Tyrannosaurus Rex, Triceratops and Pachycephalosaurus were part of this amazing ecosystem. Other dinosaur such as Edmontosaurus, Thescelosaurus, Struthiomimus and Oviraptorids existed here as well. And of course there were the Dromaeosaurs Raptors that inhabited this area and preyed upon these species such as Acheropraptor and Dakotaraptor.
