The Green River Stone Company offers the finest in natural art fossil fish and stone products. Their medium is fossil-rich calcium carbonate shale from their private quarry in Southwestern Wyoming. From this stone, deposited 50 million years ago as sediment in a large freshwater lake, they produce individual fossil specimens, artistic fossil murals, and other stone products for museums, private collectors, interior designers and architects. All fossil fish are collected and prepared in adherence to strict guidelines established by the American Association of Paleontological Suppliers Code of Ethics, State and Federal Laws. Earth Elements is proud to offer designs from The Green River Stone Company.
