4 inch Diplomystus Fossil from the famous Kemmerer Fossil Beds.

Because fifty million Years Ago an ancient lake existed in what is now Southwestern Wyoming these fish are found at over 7,000 feet above sea level. The unusual chemistry of the lake prevented decay  and scavenging of dead organisms like these fish. They are preserved in laminated “Lithographic” limestone preserving details so exquisitely that these creatures seem like they could have died recently. The bones are clearly visible dark brown on this cream colored rock.
