Oligocene The third geological epoch of the
Tertiary period. It began about 38 million years ago, following the Eocene epoch, and extended for about 13.5 million years to the beginning of the Miocene epoch. The epoch was characterized by the continued rise of mammals; the first pigs, rhinoceroses, and tapirs made their appearance.
