23" Notogoneus Fossil Fish (Scarce Species) - Wyoming


This is a large, 23" 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. This layer produces much darker and more detailed preservation than the split fish layers. The fish is completely natural with no restoration on a nice solid slab of shale.

We can add a backing and french cleat wall hanger to the piece 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.
