Epihippus is believed to have evolved from Orohippus , which continued the evolutionary trend of increasingly efficient grinding teeth. Epihippus had five grinding, low crowned cheek teeth with well formed crests. A late species of Epihippus , sometimes referred to as Duchesnehippus intermedius , had teeth similar to Oligocene equids, although slightly less developed.

Pliohippus arose in the middle Miocene , around 12 million years ago, probably from Calippus . It was similar in appearance to Equus genus Equus , Citation needed date January 2009 but had two long extra toes on both sides of the hoof, externally barely visible as callused stubs. The long and slim limbs of Pliohippus reveal a quick footed steppe animal. Until recently, because of its many anatomical similarities, Pliohippus was believed to be the ancestor of the present day horse and its relatives in Equus . Although Pliohippus clearly is an equid and thus related to Equus , its skull had deep facial fossae , a feature not found in any member of Equus . Additionally, its teeth were strongly curved, unlike the very straight teeth of modern horses. Consequently, it is unlikely to be the ancestor of the modern horse instead, it is likely to be the ancestor of Astrohippus . ref MacFadden, B. J. 1984 . Astrohippus and Dinohippus . J. Vert.

In the equid s horses and some rodent like species such as the desert hyrax , the guttural pouch is a pair of air chambers in the neck just behind the skull and below the ears. These pouches are on both sides of the head and are air filled out pouching or evagination to the Eustachian tube, leading into the Vertebrate trachea trachea . While the location of the pouches is generally understood, their purpose is not. Currently, researchers believe the pouches serve to cool blood flow to the brain during extended strenuous exercise. ref http treatmentofdiseases.blogspot.com 2006 01 mysterious guttural pouch.html ref Due to the general inaccessibility of the pouches, they can be an area of infection by molds and bacteria, and these infections can be extremely severe and hard to treat.
