Hagerman Fossil Beds National Monument Park

Rank: 321

Park Description

Did you know horses evolved in North America? The Hagerman Horse, Equus simplicidens, was the first true horse but its bones most closely resembled Grevy's zebra bones. Hagerman is home to over two hundred different species of fossil plants and animals: including sabertooth cat, mastodon, bear, camel, ground sloth, and many other species. Over 3,000 new fossil fragments are found each year.
