Did you know that one of the earliest horses lived in North America? Equus Simplicidens, also known as the Hagerman Horse, is Idaho’s state fossil. She was also the first true horse. It was about the size of a modern Arabian horse. However, its bones most closely resembled those of a zebra.
Hagerman is home to over two hundred different species of fossil plants and animals. And, if you come out over memorial day weekend, May 25 – 27, you can experience all this fascinating history, plus tons of other fun diversions!
The list of fossilized creatures from this area includes Sabertooth Cat, a Hyena-like dog, Peccary, Mastodon, Otter, Bear, Shrew, Camel, and Ground Sloth and more. With over 3,000 new fossil fragments found each year, it is one of the most fossiliferous Pliocene-aged sites in the world. The monument also includes a portion of the Oregon Trail.
