SUPPLEMENTARY INFORMATION:

Ashfall Fossil Beds is the only location on earth where large numbers of fossil mammals have been found as whole, three-dimensionally preserved skeletons. A thick bed of volcanic ash contains hundreds of complete skeletons of extinct rhinos, camels, three-toed horses and many other vertebrates lying in their death poses in an ancient waterhole. The animals were killed and buried by ash from an enormous volcanic eruption some 10 million years ago. This site is a Nebraska State Historical Park and is open to the public. Information on the National Natural Landmarks Program can be found in 36 CFR part 62 or on the Internet at http://www.nature.nps.gov/​nnl.
