22" Huge Fossil Fish (Notogoneus) - Wyoming

This is a huge, 22" long Notogoneus osculus, one of the more uncommon fish found in the Green River Formation. It was collected recently from the Clear Creek Quarry, near Kemmerer, Wyoming. It is nicely prepared and centered on a 26 x 11.8" rectangularly cut slab of shale.

The rock is just over 1" thick and is accompanied by a metal display stand. Upon request we can install a backing and wall mounting hardware upon request.

Notogoneus was a predator and the down-turned mouth is probably an indicator that it fed on prey along the lake's bottom. It is thought that its scarcity results from the fact that it's believed to have migrated between the lake and the rivers that fed it, throughout the year.

About Fossil Lake

50 million years ago, in the Eocene epoch, these fish thrived in Fossil Lake, which was fed by the Uinta and Rocky Mountain 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: 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.
