S437 - Nicely Preserved "Diplomystus dentatus" Fossil Fish - Eocene Age from USA

Beautiful and nicely preserved Diplomystus dentatus fossil fish from the Green River Formation of Wyoming (Eocene Age). Complete example of these fossil herring fishes. The specimen its wonderfully detailed with skull bones, vertebrae, ribs and fins easily seen. The specimen its completely natural and have not undergone any restoration or preservation treatment. The level of detail is spectacular.  It only has been lightly excavated around its outline to make it stand out (highlight)

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
