Fossils of the Hagerman Horse / An Idaho Adventure

 Horses From Spain

When we talk about the horse in North America we think about the Spaniards who first brought their horses from Europe to New Spain. This occurred circa 1519.

The Spanish offered many wonderful things that Native Americans found useful and beautiful. These included iron for tools, weapons, glass beads, mass produced pottery. The most life changing possession for the Indian was the horse. Before horses, dogs were the only pack animals on the plains. The harnesses and equipment originally designed for dogs were easily redesigned for horses. Horses of course could carry much larger loads than a dog.

Horses in North America Prior to the Spaniards

Soon after they discovered America, the Spanish reintroduced horses to the continent. The Spanish horses were from the finest strains and were regarded as the top breed in Europe. They were also prized by North American plains Indians. Stallions and mares that escaped from the Spanish were what formed the nucleus of the great herds of wild horses that spread upward from Mexico, into Texas and northward into the western Plains country. These herds of wild horses were generally referred to as Mustangs.These were the horses captured by the Native Americans that changed their daily lives.

The Hagerman  / The First North American Horse

Interestingly enough there was another breed of horse on the North American continent  which became extinct between 13,000‐11,000 years ago.

Most believe that the ancient North American horses became extinct during the Paleo Indian period. This was perhaps 10,000 years ago. These early horse species were decimated by climatic changes and eventually vanished completely from North America. At about the same time in Europe and north Africa, horses were becoming common in many ancient civilizations.

Around 3,000 years ago, horses were domesticated in Europe for the first time. Just like the Spanish horses that arrived in North America centuries later they were used for transportation for humans and cargo. About five hundred years after that, Persian officials began using mounted couriers to convey messages back and forth.

The Hagerman Horse, Idaho’s state fossil, was the first true horse on the North American continent.  The Hagerman horse fossil was designated the official state fossil of Idaho in 1988. This horse was about the size of a modern Arabian horse but it's bones most closely resembled those of the Grevy’s zebra. Over two hundred individual fossils of both sexes and all ages were recovered by the Smithsonian. Included are complete skeletons as well as skulls, jaws and detached bones.

A Great Idaho Fossil Discovery

The discovery of this magnificent fossil bed goes back to 1928 when a local cattle rancher was digging on a  bluff in the Hagerman Valley and discovered fossilized bones. Curious of his find, the rancher took a few of the horse like bones to a local scientist who after examining them passed them on to the Smithsonian. The Smithsonian was aware they were on to something and organized an expedition to the Idaho site. The Smithsonian expedition  ended up recovering over three tons of fossils including five full horse skeletons. Several times the Smithsonian returned to the site that became known as the "horse quarry".The Hagerman horse is one of the oldest horse fossils ever discovered.
