Diplomystus is an extinct genus of freshwater clupeomorph fish distantly related to modern-day extant herrings, alewives, and sardines. Phareodus was a genus of freshwater fish from the Eocene to the Oligocene of Australia, Europe and North America, with an oval outline, a small head, and a slightly pointed snout. Priscacara is an extinct genus of perch from the middle Eocene, characterized by a sunfish-like body and stout dorsal and anal spines. Mass deaths of Priscacara suggest it formed schools. A small schooling fish, Knightia made an abundant food source for larger Eocene predators. Quarried from Mosaic Lake and unearthed by hand, this striking mural contains a 16″ Diplomystus, 6.5″ Phareodus, 8.5″ Priscacara, and 4 Knightia.
