Eohippus was very different to our modern horse – so much so that at first it wasn't believed to be related at all. Between 4.2hh and 5hh, it was the size of a fox, and had an arched back and raised hindquarters. Its teeth were adapted for a browsing diet- eating leaves, fruit, and shoots of shrubby plants.
When Sifrhippus sandae, the earliest known horse, first appeared in the forests of North America more than 50 million years ago, it would not have been mistaken for a Clydesdale. It weighed in at around 12 pounds--and it was destined to get much smaller over the ensuing millennia.
The basic storyline goes like this: as the woodlands of North America gave way to grassy plains, the tiny proto-horses of the Eocene Epoch (about 50 million years ago) gradually evolved single, large toes on their feet, more sophisticated teeth, larger sizes, and the ability to run at a clip, culminating in the modern ...
EOHIPPUS. The first equid was Hyracotherium, a small forest animal of the early Eocene. It looked nothing at all like a horse (10 – 20” hight). It resembled a dog with an arched back, short neck, short snout, short legs, and long tail.
During the early Eocene there appeared the first ancestral horse, a hoofed, browsing mammal designated correctly as Hyracotherium but more commonly called Eohippus, the “dawn horse.” Fossils of Eohippus, which have been found in both North America and Europe, show an animal that stood 4.2 to 5 hands (about 42.7 to 50.8 ...
Their work revealed that the majority of medieval horses, including those used in war, were less than 14.2 hands (4 feet 10 inches) tall from the ground to their shoulder blades—the maximum height of a pony today, according to Matthew Hart for Nerdist.
On average, horses from the Saxon and Norman periods (from the 5th through 12th centuries) were under 1.48 meters (4.9 feet) or 14 hands high – ponies by modern size standards. A hand is 4 inches (10.2 centimeters) and the main unit to measure the height of horses and ponies.
Ancient Horses
Here, two large Dinohippus horses can be seen grazing on grass, much like horses today. But unlike modern horses, a three-toed Hypohippus tiptoes through the forest, nibbling on leaves. A small, three-toed Nannippus, shown here eating shrubs, ate both grass and leaves.
As horses' legs grew longer, the extra toes at the end of the limb would have been “like wearing weights around your ankles,” McHorse says. Shedding those toes could have helped early horses save energy, allowing them to travel farther and faster, she says.
The modern horses that we are used to only represent one small branch of the HUGE family tree known as the Equidae. This tree spans over millions of years and all other branches are sadly extinct, but we do know that the earliest known horses evolved 55 million years ago.
The earliest horses had three or four functional toes. But over millions of years of evolution, many horses lost their side toes and developed a single hoof. Only horses with single-toed hooves survive today, but the remains of tiny vestigial toes can still be found on the bones above their hoofs.
Thus the classic story of horse evolution was formed: as grasslands took over from forests, the horse gradually evolved larger body size (perhaps to better defend against predators), taller-crowned teeth to handle abrasive grasses, and long, monodactyl limbs to race away from predators in their newly open habitat (Fig.

“Big Jake” was a 20-year-old Belgian who lived on Smokey Hollow Farm, an 85-acre farm in Poynette. Big Jake was also the Guinness World Record holder for the world's tallest living horse.
Eohippus, (genus Hyracotherium), also called dawn horse, extinct group of mammals that were the first known horses. They flourished in North America and Europe during the early part of the Eocene Epoch (56 million to 33.9 million years ago).
Old Billy (also called Billy or Ol' Billy) was the longest-living horse on record. Old Billy was verified to be 62 at his death. Born in Woolston, Cheshire, England in 1760, Billy adventured and became a barge horse that pulled barges up and down canals.
Because horses can not stay off their feet for long periods, broken bones do not have a chance to heal, and so often sadly the kindest way to help a horse with a broken limb is to put it down.
Often the only humane option after a horse breaks its leg is to euthanize it. This is because horses have heavy bodies and delicate legs, and broken leg bones are usually shattered making surgery and recovery impossible.
Breaks in horses can also be much more severe than in a human or other mammals, because of their weight and the fragility of their legs. “Because of the high energy impact, the horse can shatter that bone, more than just a simple crack, making repair much less likely,” Palmer said.
A dramatic “event” of this time period was the last “Ice Age.” The Pleistocene Epoch also was the last time that a great diversity of mammals lived in North America, including mammoths, mastodons, giant sloths, several llama-like camels, and tapirs. And it was the last epoch native horses lived in North America.
Horses were abundant across North America, Eurasia and Europe during the Ice Age. In fact, palaeontologists throughout the 20th and 21st centuries have defined over 50 different species of ice age horse based on the size and shape of their skeletons.
Horses became a taboo meat in the ancient Middle East, possibly because they were associated with companionship, royalty, and war. The Book of Leviticus rules out eating horse, and in 732 Pope Gregory III instructed his subjects to stop eating horse because it was an “impure and detestable” pagan meat.
Many of our employees often comment that the horses are treated better than anyone else within the company – and although they say it jokingly, it's really quite true. The horses that you saw drooling were the Andalusian stallions. They drool for a number of reasons – none of which are negative.
The reason large horses were so effective in warfare and in tournaments was because their weight gave greater force to the impact of the knight's lance. By the 14th century, an average warhorse would weigh between 1,200 and 1,400 pounds and stand approximately 14 to 15 hands.
Recent research undertaken at the Museum of London, using literary, pictorial and archeological sources, suggests war horses (including destriers) averaged from 14 to 15 hands (56 to 60 inches, 142 to 152 cm), and differed from a riding horse in their strength, musculature and training, rather than in their size.
