A small schooling fish, Knightia made an abundant food source for larger Eocene predators. 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. Diplomystus is an extinct genus of freshwater clupeomorph fish distantly related to modern-day extant herrings, alewives, and sardines. Quarried from Mosaic Lake and unearthed by hand, this breathtaking mural contains 3 Knightia eocaena, a Priscacara liops, a 15.5″ and a 10.25″ Diplomystus dentatus.
