Many fascinating fossils have been discovered at the Hagerman Fossil Beds National Monument. These include the Hagerman horses, saber-tooth cats, mastodons, and the Bone-Crushing canid.

The land protected by the National Park Service at the Hagerman Fossil Beds National Monument protects not only a rich paleontological history but a human history too.

The human story told at Hagerman Fossil Beds National Monument is one of two cultures colliding during the growth of a nation. The Hagerman Fossil Beds National Monument contains a portion of the Oregon Trail.

Hagerman Fossil Beds and the Oregon Trail

The Shoshonean people have called the Hagerman Valley home for thousands of years. The Shoshonean tribes made their camps along the Snake River because of the plentiful supply of Salmon.

In the 1840s, the Shoshonean way of life was interrupted as the Oregon Trail saw increased traffic. The Oregon Trail cuts through the southern part of the National Park. The Hagerman Valley was used as a stop along the Oregon Trail by travelers because of the Snake River.

Initially, the Shoshonean people who lived in the area traded with the emigrants. As the number of people using the Oregon Trail increased, the resources in the area became strained. A further strain was placed on the resources when several emigrants decided to settle permanently in the Hagerman Valley and its surrounds.

Conflict between the settlers and the Shoshonean tribes erupted in the area. In 1868 the United States government sought to end the violence with the Fort Bridger Treaty of 1868. This treaty removed the Shoshonean people from the Hagerman Valley and onto reservations.

By the 1870s, ranchers and gold miners had settled in the area. The area became home to a small community of agricultural farmers. In 1928, one such farmer by the name of Elmer Cook decided to contact the Smithsonian Institution. Cook believed the fossils visible on the bluffs above the Snake River were important.

The Fossils of Hagerman Fossil Bed National Monument

Millions of years before the area was inhabited by humans, the Hagerman Valley was home to hundreds of different species of plants and animals.

During the Pliocene Epoch, the region that now consists of scrub was once wetlands, forests, and grassland. Hagerman Valley was once as diverse ecologically as the species that thrived here.

The fossils found in the Hagerman Fossil Bed were eroding out of the steep bluffs around the Snake River. The fossils found in the Hagerman Valley are believed to contain an entire Pliocene ecosystem.

Excavations began at the Hagerman Fossil Beds National Monument in 1929 by a team from the Smithsonian Institution in Washington, D.C.

The Smithsonian Excavations

Teams from the Smithsonian had active excavations in the area in 1929, 1929, 1930, 1931, and 1934. The park is home to the world’s largest collection of Equus simplicidens, also known as the Hagerman horse. Over 200 Hagerman horse fossils were found at the site.

The discovery of the Hagerman horses has helped scientists to understand the evolution and migration of ancient horses that eventually led to the domestication of the species by humans. The Hagerman Horse is the ancestor to the horses, donkeys, and zebras we see today.

The fossil beds are home to many more species than just the Hagerman horse. The region was home to the Bone-Crusher or Borophagus hilli, a canid resembling a hyena.

These dog-like creatures roamed the Hagerman Valley over 3 million years ago, scavenging and hunting. They were carnivores who could crush bone with their powerful jaws. They have no living ancestors.

During the 1934 excavation, a team discovered a new species in the Hagerman Fossil Beds, the Platygonus Pearcei, an Ancient Peccary.

Although this species of pig-liked hoofed mammals are now extinct, its relatives still roam the earth. The Platygonus Pearcei are related to the Peccaries inhabiting South America and the Southwestern United States.

Excavations in Hagerman Valley also revealed the fossilized remains of the American mastodon. The large mammal lived in the cool forests of the region during the Pliocene. The mastodon is very distantly related to modern elephants and the extinct mammoth.

Today there are no active excavation sites, but the collection of fossils from the surface is ongoing, as is the scientific research.
