A Brief History of Horses. By 55 million years ago, the first members of the horse family, the dog-sized Hyracotherium, were scampering through the forests that covered North America. For more than half their history, most horses remained small, forest browsers.
The dawn horse was a form close to the common ancestry of all the odd-toed hoofed mammals, the perissodactyls. It stood 30â60 cm (1â2 feet) high at the shoulder, depending on the species. The skull varied in length; some species had a relatively short face, but in others the face was long and more horselike.
