Green River Formation
Quick Summary
The Green River Formation is a geological feature in the western United States, primarily found in Wyoming. It is known for preserving an extensive record of fossilized freshwater fish from the early Eocene Epoch, approximately 50 million years ago. This formation, composed of lake sediments, has yielded remarkably intact fossils of over 20 fish species, numerous insects, plants, and other ancient life forms. It is a significant paleontological site, offering insights into prehistoric ecosystems. The formation is also associated with the Green River, a major river in the western United States that flows through Wyoming, Utah, and Colorado.

The Green River formation, an oil-shale formation in Colorado, Utah, and Wyoming, is a potentially valuable source of synthetic crude oil. In eastern Germany and Poland the Kupferschiefer, a bituminous shale, is mined for copper, lead, and zinc.
