From Wikipedia, the free encyclopedia
The Green River Formation is a famous Konservat-Lagerstätte located in the Intermountain West of the United States, in the states of Colorado, Utah, and Wyoming. It comprises sediments deposited during the Early Eocene in a series of large freshwater lakes: Lake Gosiute, Lake Uinta, and Fossil Lake (the last containing Fossil Butte National Monument). It preserves a high diversity of freshwater fish, birds, reptiles, and mammals.
