The Green River Formation is one of the best-known fossil deposits in the US. It was deposited in a group of lakes in Wyoming, Colorado, and Utah during the tropical middle of the Eocene Epoch, about 50 million years ago. The best-known fossils from the Green River Formation are the fishes, of which countless examples have been collected over the past 150 years or so.
Fossils here were discovered even before the railroad came through in the late 1860's although railroad cuts exposed the first major deposits of fossil fish. Scientific and amateur collections started before the turn of the century and continue today. Thousands of fossil fishes are collected every summer from the commercial quarries in southwestern Wyoming. But there are more than fishes found here, including many species of Eocene birds and other animals. This talk will be a survey of paleontology of the Green River Formation.
