Our quarries are located near Kemmerer, Wyoming - home of Fossil Butte National Monument. Warfield Fossil Quarries are part of the Green River Lake system, and are located in the Fossil Lake Basin.
The fossils found in the Green River Foundation are between 40-60 million years old (Eocene Age), and are in excellent preservation. After collection, the fossils are cleaned and prepared in our studio 120 miles north of the quarry in Thayne Wyoming.
We specialize in the collection and preparation of fossils for private and public collections world-wide.
