Scientific name: †Knightia eocaena + Diplomystus dentatus - Fossil Fish Mass Mortality Plate with 2 specimens Location: Kemmerer, Wyoming, USA Geological Formation: Green River Formation Age: Paleogene, Eocene (~48-51 million years) Size: Plate size: 12,5x17,5x1,5cm - The biggest fish: 10cm Diplomystus dentatus REF.: #S363 DESCRIPTION: Observations: Beautiful mass mortality plate of the fossil fish Knightia eocaena and Diplomystus dentatus from the Green River Formation of Wyoming. There 2 almost complete example of these fossil herring fishes. The specimens are wonderfully detailed with fins easily seen. The specimens are completely natural and have not undergone any restoration or preservation treatment. The level of detail is spectacular. 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 Plate size: 12,5x17,5x1,5cm - The biggest fish: 10cm Diplomystus dentatus IMPORTANT SHIPPING INFORMATION: Our company is based in the USA, but our headquarters and products are located in Europe.
