Near Kemmerer in Lincoln County, Wyoming — The American West (Mountains)
Fossil Lake was the smallest and shortest-lived of the Green River System lakes. At its largest size, the lake covered 932 square miles and existed for approximately three million years. One phenomenon of the Fossil Lake fossils is their density. There are as many as several hundred fossilized fish per square meter in some portions of Fossil Butte. At least thirteen genera of fish are found in the sediments of fossil lake, as well as a wide variety of species, from large predators like gar and bowfin to the now extinct Knightia, Diplomystus, and Priscacara. Plant and invertebrate records are equally diverse. Evidence of lily pads, horsetails, ferns, palms, and poplar
The paleontologist who worked at Fossil Butte have deposited specimens at the Field Museum in Chicago, IL, the American Museum of Natural History, in New York City, and Smithsonian Institution’s National Museum of Natural History in Washington D.C.
