Paleobiota of the Green River Formation

The Green River Formation is a geological formation 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, with some sections of the formation (including Fossil Lake and the Parachute Creek member of Lake Uinta) qualifying as Konservat-Lagerstätten due to their extremely well-preserved fossils.
