around the same time, camels were becoming common in north america, although they were just barely bigger than modern rabbits during the eocene. early camels had four toes. during the early part of the eocene the first primitive horses also began appearing. among the earliest was "eohippus", a small animal with four toes on the front feet and three on the rear. a group of mammals called oreodonts also appeared during the eocene. by the oligocene, camels were the size of sheep and had only two toes. gradually over time horses also lost toes, but unlike camels, horses' were reduced to a single digit. by the oligocene their teeth had adapted to endure abrasion from silica in their increasingly grassy diets. horses gradually became common throughout the country. large numbers of oreodonts grazed in the badlands of south dakota by the middle of the cenozoic. oreodonts were vaguely pig like and about the size of modern goats. their numbers peaked during the oligocene. the largest mammals of oligocene north america were the rhinoceros-like titanotheres. one spectacular example was the abundant "brontotherium" of south dakota, which could be up to 8 feet tall at the shoulder. despite their early success, by the end of the epoch the entire group became extinct.
