19" Notogoneus Fossil Fish (Scarce Species) - Wyoming

This is a 19" long Notogoneus osculus, one of the larger and more uncommon fish found in the Green River Formation. It was collected from the 18 inch layer of the formation at Warfield's Quarry near Kemmerer, Wyoming. This layer produces much darker and more detailed preservation than the split fish layers.

There is some restoration to the fins of the fish. The plate has been backed with Hardie Board, a fiberglass/concrete composite for stability and to make it easier to install mounting hardware. We can install a french cleat hanging system for no charge upon request.

The lake itself is known as "Fossil Lake" and it existed 50 million years ago in what is now Wyoming and is believed to have covered approximately 930 square miles. It had an unusual chemistry that inhibited the decay and scavenging of dead organisms while think layers of limestone and organic matter accumulated. This special set of circumstances has lead to the beautiful preservation of fish and other fossils within the Green River Formation.
