Eohippus is small fossil proto-horse. It is an extinct genus of small equid ungulates.[1] The only species is E. angustidens, which was long considered a species of Hyracotherium. Its remains have been found in North America and date to the early Eocene (48–56 million years ago).[2]

Much of the evolution of the horse took place in North America. That is where horses originated, but became extinct there about 10,000 years ago.[3]
