12" Rock With Three Fossil Fish (Mioplosus) - Wyoming

This is a solid, 11.8" wide section of shale with three jet black fossil fish (Mioplosus labracoides). It comes from the Green River Formation near Kemmerer, Wyoming. Mioplosus is one of the more uncommon fish found in the formation, so finding three on a single piece of rock is quite rare. These fish measure 5.1", 5" and 4.9" long.

This specimen comes with a display stand.

50 million years ago, in the Eocene, these fish thrived in Fossil Lake, which was fed by 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 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.
