11.8" Large Fish Fossil (Mioplosus) - Wyoming
This is a 11.8" long, fossil fish (Mioplosus labracoides) from the Green River Formation of Wyoming. Mioplosus is one of the more uncommon species from formation. It's nicely centered on a solid, rectangularly cut slab of shale and comes with a 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.
