RECENT, 10,000 years ago to Present. The modern day species of Equus (horses, zebras, and asses) have been around for about 2 million years. They are very different from the earliest known horse, Hyracotherium, otherwise knows as Oehippus, or âDawn Horseâ. This ancient horse was a small, dog-sized creature that lived from 55 to 45 million years ago.
Equines are both heterodontous and diphyodontous, which means that they have teeth in more than one shape (there are up to five shapes of tooth in a horse's mouth), and have two successive sets of teeth, the deciduous (baby teeth) and permanent sets. fully developed horse of around five years of age will have between 36 and 44 teeth. All equines are heterodontous, which means that they have different shaped teeth for different purposes. All horses have twelve incisors at the front of the mouth, used primarily for cutting food, most often grass, whilst grazing.
