Three Detailed Fossil Fish (Knightia & Diplomystus) - Wyoming

This is a trio of beautifully preserved of fossil fish (Diplomystus dentatus & Knightia eocaena) from the Eocene aged Green River Formation of Wyoming. It is very nicely detailed and prepared with bone structure, fins, and the overlapping scale structure visible. The largest fish on the piece is 4.2" long and the entire piece of shale is 6.9 x 5.5"

Comes with an acrylic 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.
