Fish Fossil - Knightia Eoceana Pyrite Originating from the famed GreenDuring the Eocene, 40 50 million years ago, vast shoals of freshwater fish inhabited a large shallow inland sea across the American West. The herring like fish of the genus Knightia were far and away the most abundant freshwater fish during this era, and because of this they are one of the most frequently found vertebrate fossils on earth. Originating from the famed Green River Formation in Wyoming, fossils of Knightia eocaena and their close
