6.9" Uncommon Fish Fossil (Mioplosus) - Wyoming

This is a very detailed, 6.9" long fossil fish (Mioplosus labracoides), one of the more uncommon species from the Green River Formation. It was collected from a quarry near Kemmerer, Wyoming. Excellent preservation and preparation. You can even see scale preservation over much of the fish.

It is accompanied by an acrylic display stand.

50 million years ago, in the Eocene, 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.
