15.4" Fossil Fish (Mioplosus & Knightia) Plate - Wyoming

These are two detailed fossil fish (Knightia eocaena and Mioplosus labracoides) collected from the Green River Formation. They were collected from the Lindgren Quarry near Kemmerer, Wyoming. Both fish show excellent preservation of bones and fin rays and are nicely centered on a rectangular-cut, 15.4 x 11.2" slab of shale.

The Knightia is 4.2" long and the Mioplosus measures 4.95" long. Comes with an acrylic/metal display stand.

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.
