Large, 8" Priscacara Fossil Fish With Knightia - Wyoming

Large, Priscacara Fossil Fish With Knightia - Wyoming #189308

These are two nicely preserved fossil fish from the Eocene age Green River Formation of Kemmerer, Wyoming. The Priscacara serrata fish is quite large and detailed, bearing wonderfully preserved bone, scale and fin preservation. It measures just over 8" wide and is naturally associated with a 4.5" wide Knightia fish fossil.

Comes with an acrylic/metal (gibson) display stand.

50 million years ago, in the Eocene, 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.
