InGen Database Description
The Cedar Mountain Formation is a geologic formation situated in eastern Utah. It's named after Cedar Mountain where William Lee Stokes first investigated it in 1944. It lies between the Morrison Formation beneath and the Naturita Formation above. It has been dated to the Early Cretaceous epoch, 120 million years ago.
The formation is formed from layers of non-marine sediments including the deposits from rivers, lakes and floodplains.
Studies on the dinosaur fossils here didn't start until the 1990s. So far, the finds appear to form two different sets. The lower layers contain older dinosaurs similar to European dinosaurs of the age, while the upper finds are similar to the younger Asian dinosaurs. This discrepancy is caused by the continental drift as North America moved westward.
It is known as one of the most productive Early Cretaceous locations for fossil finds. A wide variety of dinosaurs, fish, amphibians, birds and mammals have been discovered, as well as many others.
