DIPLOMYSTUS AND KNIGHTIA NATURAL DOUBLE FISH ON MATRIX Green River Formation - Kemmerer, Wyoming, U.S.A. EOCENE PERIOD: 54 million years ago From the famous Green River Formation in Wyoming, this beautiful natural double of a large Diplomystus dentatus fish above a smaller Knightia species fish. Both fish are genuine and were found slightly overlapping in this beautiful and aesthetic manner. Each of these fish are well preserved but the Diplomystus is not only a superb example with heavy detail but it is a very large example of this much more rare species than is One of the most important fossil sites for understanding the Eocene is found at Green River, located in western Colorado, eastern Utah and southwestern Wyoming in the United States. During the Eocene, this region was located at much the same latitude it is today, though global climate was more equable. Therefore, the climate in which the organisms lived differs somewhat from that of the present-day western United States. The fossils, especially plants, found at this site indicate that the climate was moist temperate or sub-tropical, with temperatures ranging from 15 to 20 degrees Celsius. In addition to the plants, another piece of evidence suggesting that the climate was sub-tropical was the presence of fossilized crocodiles. Crocodiles can only survive in areas with a constant, warm temperature. If you were able to visit the Green River locality during the Eocene, you would see palms, cat-tails, sycamores, and other familiar plants from North America, but you would also see some that are today more common in, or restricted to, eastern Asia. A series of large inland lakes extended across the region, and it is in the bottoms of these lakes that various plants and animals were buried and fossilized. These lakes later dried up as the local climate changed, and many of the plants and animals living there became extinct.
