Of the true ruminants the Tylopoda, or camels and Pier-casellamas, seem to have originated in Xorth America, where ^*they can be traced liack by fossils from the Pliocene andMiocene formations to a little ga2:elle-sha])ed creature of theOligocene period, Poehrothninm.

The giratfes, or GirafRdae, have always been Old Worldquadrupeds. Though now contined to Africa, they alsoranged over the greater part of Asia and southern Europe inthe Lower Pliocene Period, as shown by fossils from China,India, and Greece in Pier-case 14. Even the long-limljedand long-necked Giraffa itself was in existence at that time,but it seems to have l^een less common than the antelope-shaped relatives of the okapi, which has only escapedextinction l\y retreating to the recesses of the Semliki fo
