Reconstruction, left forefoot skeleton (third digit emphasized yellow) and longitudinal section of molars of selected prehistoric horses Skeletal evolution. The evolution of the horse, a mammal of the family Equidae, occurred over a geologic time scale of 50 million years, transforming the small, dog-sized, [1] forest-dwelling Eohippus into the ...

Equus scotti is a true caballine horse that is more closely related to modern horses than to zebras and asses. Equus scotti may be synonymous with Equus lambei , another generally smaller horse known from the Pleistocene of North America, but this is uncertain. [ 3 ]

Restoration by Charles R. Knight. Mesohippus had longer legs than its predecessor Eohippus and stood about 60 cm (6 hands) tall.This equid is the first fully tridactyl horse in the evolutionary record, with the third digit being longer and larger than its second and fourth digits; Mesohippus had not developed a hoof at this point, rather it still had pads as seen in Hyracotherium and Orohippus ...
Equidae (commonly known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, asses, and zebras, and many other species known only from fossils. The family evolved more than 50 million years ago, in the Eocene epoch, from a small, multi-toed ungulate into larger, single-toed animals.
Equus simplicidens, also known as the Hagerman horse and American zebra, is an extinct species of equine native to North America during the Pliocene and Early Pleistocene. [1] It is one of the oldest and most primitive members of the genus Equus .
Merychippus was the first equine to have the distinctive head shape of today's horses. The Miocene was a time of drastic change in environment, with woodlands transforming into grass plains. [ 7 ] This led to evolutionary changes in the hooves and teeth of equids .
