Southwest Wyoming’s Green River Formation has preserved spectacular, detailed, and complete fish fossils from the Eocene Epoch of approximately 50 million years ago. Diplomystus is an extinct genus of freshwater clupeomorph fish distantly related to modern-day extant herrings, alewives, and sardines. This beautiful piece of prehistoric fossil art contains a left-facing Diplomystus.
