Scientific name: Knightia eocaena
Location: Kemmerer, Wyoming
Geological Formation: Green River Fm
Age: Eocene ( 56 million years)
Size: 11,1cm long - Plate: 14,8 x 20,2cm
Ref: M86 -13021
Fifty million years ago ancient Fossil Lake existed in what is now southwest Wyoming.
The unusual chemistry of fossil lake prevented decay and scavenging of dead organisms while millimeter-thick layers of alternating limestone matter slowly accumulated. The result is laminated limestones that contained the highest concentration of fossil fish in the world.
Since the discovery in the 1870's, many perfectly preserved fossil fish have been recovered. Preserved with the fish in the laminated limestone is a complete aquatic ecosystem: plants, insects, crustaceans, amphibians (frog and primitive salamander), alligators, turtles, birds, mammals, etc
