- Phareodus sp.
- Eocene Age
- Green River Formation
- This specimen measures approx. 11 1/4″ long. The overall size of the plate measures approx. 13 1/4″ x 23″. There is an unprepared Mioplosus Skeleton visible on the matrix that measures approx. 8 1/2 as an added bonus… this is a great plate! (There is a backer board attached to the plate for added strength)
Phareodus is a genus of freshwater fish from the Eocene to the Oligocene of Australia and North America. These fish existed 50 million years ago during the Eocene epoch. Today their ancestors and close relatives, the “bonytongues”, live throughout the world. Phareodus are well known for their long pectoral fins, large scales, and several pointy teeth. These fish are suggested to be active hunters due to their array of sharp teeth.
Also, the remnants of Priscacara and Mioplosus percoid spines have been found in their stomachs. They may have had organs that enabled them to “breathe air” like today’s Arowana and Arapaima. Their jaws are hinged at the bottom (like the Arowana’s) which might mean they spent most of their time at the surface. Phareodus may have been mouth-brooders like most modern-day bonytongues. The average length of Phareodus fossils are 7 inches (17.8 centimeters) with a maximum size of 30 inches (76.2 centimeters). Phareodus fossils are labled uncommon. During life, Phareodus most likely fed on Knightia, Priscacara, and other small fish.
