7.7" Shale With Five Fossil Fish (Knightia) - Wyoming

This is a 7.7" plate of fossil fish (Knightia) from the Green River Formation of Wyoming. They are very nicely detailed and prepared with bone structure, fins and scales visible. This plate contains five fish, the longest is approximately 2.2" long. The reverse side of this specimen has a number of fish (Knightia) fragments and two coprolites (Feces).

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.
