Fossils are evidence of ancient life. They are irreplaceable pieces of America's geologic heritage and tell the stories of America long before the United States existed. Fossils are found in the rocks, museum collections, and cultural contexts of more than 270 National Park Service areas and span every period of geologic time from billion-year-old stromatolites to Ice Age mammals that lived a few thousand years ago.
