//Wyoming- Knightia eocaena//


 * ===The Knightia is an extinct genus of fish that was slender usually about 6 inches long, and seemed to have been a secondary consumer, feeding mainly on ostracods, algal forms and diatoms, as well as some smaller fish. They were schooling fish, which we know because they are frequently found together in mass mortality layers. ===




 *  This fish was found during the Eocene epoch which began 10 million years after the extinction of the dinosaurs, 65 million years ago, and continued for another 22 million years.The Eocene epoch was when the first prehistoric whales left dry land and opted for a life in the sea, a trend that culminated.
 * Preservation: This fish was actually found in abundance in the Green River Formation in Wyoming, so if you really wanted to you could buy from the state of Wyoming.
 * Geologist Dr. John Evans collected the first fossil fish, described as //Culpea humilis// which was later renamed //Knightia eocaena//, from the Green River beds in 1856.
 * Knightia became Wyoming's State Fossil on February 18, 1987.
