7.5" Diplomystus With Knightia Fossil Fish - Wyoming

This is a 14" wide slab of shale containing three well preserved fossil fish from the Green River Formation of Wyoming. The larger fish is a 5.8" long Diplomystus dentatus and it is associated with a pair of Knightia eocaena. It's a thick, solid slab of shale and it comes with a display stand.

50 million years ago, in the Eocene these fish thrived in Fossil Lake fed by Uinta and Rocky Mtn. 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.
