Ashfall Fossil Beds State Historical Park

Ashfall Fossil Beds State Historical Park in Nebraska is a preserved site rich in well-preserved prehistoric fossils. About 12 million years ago, a volcanic eruption released ash that buried a diverse array of animals—rabbits, horses, camels, and even early elephants—in the area. Over time, mineralization preserved their bones and some soft tissues, providing valuable insights into ancient ecosystems. Today, the park offers visitors a chance to see these fossils in a natural setting, learn about prehistoric life, and understand how volcanic ash can create exceptional conditions for fossil preservation.
