25.2" Fossil Fish (Notogoneus) - Very Large & Rare!

This is a giant, 25.2" long Notogoneus osculus, more uncommon fish found in the Green River Formation. It was collected from the 18 inch layer of the formation near Kemmerer, Wyoming. This layer produces much darker and more detailed preservation than the split fish layers.

The plate has been backed with wood for stability and has ring hangers installed so that it can be easily hung on a wall. The entire slab of shale is 32.1 x 17"

It comes from the coveted 18 inch layer of the Green River Formation which produces darker and more detailed fish than the majority on the market. The rock from this layer is much harder and more durable. This layer is typically collected at night using low angle light to see the bump in the rock that the back bone creates. They then cut these fish out and take them to a lab where the fish which may be up to an inch under the surface of the rock are meticulously extracted under microscope with hand tools.

50 million years ago, in the Eocene these fish thrived in Fossil Lake fed by Uinta and Rocky Mtn. highlands. The anoxic conditions at the bottom of Fossil Lake slowed bacterial decomposition, prevented scavengers from disturbing corpses, and most interestingly, suffocated creatures that ventured into the oxygen-starved aquatic layer. The result is a miraculous exhibition of Eocene biota in a subtropical, aquatic community within sycamore forests teeming with creatures such as freshwater stingrays, dog-sized horses, menacing alligators, early flying bats, and one of the first primates.
