5.1" Diplomystus Fossil Fish With Two Knightia - Wyoming

Diplomystus Fossil Fish With Two Knightia - Wyoming #179307

This is a beautiful cluster of 48 million year old fossil fish from the Green River Formation of Wyoming. The Diplomystus dentatus fish measures 5.1" long and is associated with two Knightia eocaena. All three fish are located on a solid, 13" wide slab of shale.

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.
