Scientific name: Diplomystus dentatus
Location: Kemmerer, Wyoming
Geological Formation: Green River Fm
Age: Eocene ( 56 million years)
Size: 12,5cm long - Plate: 17,3 x 12,8cm
Ref: M12 - 13015
Diplomystus dentatus morphology, including its upturned mouth, is prototypic of a surface-feeding fish. The genus is herrings that likely fed on small surface-dwelling fish as Knightia is evidenced by numerous fossils found with Knightia in the stomach or mouth.
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
