The Fossil Record is the story of Earth’s epic that unfolded over billions of years. It could be likened to a movie of the history of life across all of geological time. The problem is that only a small fraction of the film’s frames was preserved. Diplomystus is an extinct genus of freshwater clupeomorph fish distantly related to modern-day extant herrings, alewives, and sardines. This beautiful piece of natural history contains a 17″ Diplomystus.
