The Duchesne River Formation is a geologic formation in the Uinta Basin of northeastern Utah. It was originally named the Duchesne Formation by Carnegie Museum paleontologist OA Peterson, and modified to the Duchesne River Formation by Carnegie Museum paleontologist JL Kay because Duschesne Formation was previously used for a Jurassic limestone. In naming the formation, no type section was given, only that it is named for the Duchesne River, which flows roughly southeast and east to join the Green River.
