Priscacara is an extinct perch-like fish that lived in North America during the Eocene Epoch, approximately 55 million years ago. This particular specimen, Priscacara serrata was found near Kemmerer, Wyoming in the world famous Green River Formation. In these beds, layers of fine grained limestone yield well preserved fossils that offer the world's most complete look at an ancient fresh water lake environment. The Green River Formation contains an abundant and diverse flora and fauna including plants, insects, fish, and the other inhabitants of the lake environment.
The Green River Formation was a system of three ancient fresh water lakes that covered parts of Utah, Colorado, and Wyoming. These Lakes covered an area of about 25,000 square miles. Lake Uinta was the longest lived, spanning nearly 18 million years. Lake Gosiute existed for about 6 million years, and Fossil Lake, the shortest lived, existed for about 2 million years. During the Eocene Epoch this area of the United States had a subtropical climate similar to today's Florida Everglades.
Priscacara serrata is easily identified by its stout dorsal and anal spines that may have protected it from being swallowed by predators. Little is known about the evolutionary origin of the Priscacara and its relatives making it one of the last mysteries among ichthyologists.
Priscacara over eight inches are rare. This little beauty is nine inches and would have sold for around $500.00 or more. The frame would have added another $150.00 to the price.
