The most common fossil fish found in the Green River Formation is Knightia. Knightia was a herring-like, schooling fish which averaged about 3-4 inches in length, though it could grow up to 10 inches long. Like many modern freshwater fish Knightia had four fins, ones on its back, stomach, pelvis, and anus. It would have eaten plankton and algae and was a food source for many of the larger fish like Mioplosus and Phareodus that also inhabited the lake.
