Knightia eocaena, an extinct schooling fish, thrived during the Eocene epoch (56–34 million years ago). Its fossils, mainly found in the Green River Formation, Wyoming, USA, offer insights into ancient freshwater ecosystems. As a primary food source for larger predators, Knightia played a crucial role in its environment, illustrating the complex food webs of prehistoric aquatic life.
