The Oligocene Era

The Oligocene Epoch 34 23 Million Years Ago Paleontology World Oligocene. base of magnetic polarity chronozone c6cn.2n. the oligocene (ipa: ˈɒlɪɡəsiːn, ɡoʊ ol ə gə seen, ⁠goh ) [4] is a geologic epoch of the paleogene period that extends from about 33.9 million to 23 million years before the present (33.9 ± 0.1 to 23.03 ± 0.05 ma). as with other older geologic periods, the rock beds. The oligocene epoch is subdivided into two ages and their corresponding rock stages: the rupelian and the chattian. it followed the eocene epoch and was succeeded by the miocene epoch, the first epoch of the neogene period. the term oligocene is derived from greek and means the “epoch of few recent forms,” referring to the sparseness of the.

In geologic time, the oligocene epoch occurs during the tertiary period (also sometimes divided or referred to in terms of a paleogene period and a neogene period) of the cenozoic era of the phanerozoic eon. the oligocene epoch is the third epoch in the tertiary period (in the alternative, the latest (most recent) epoch in the paleogene period). Oligocene epoch, major division of the paleogene period, from c. 33.9 million to 23 million years ago. it follows the eocene epoch and precedes the miocene epoch. the term (from the greek for “few recent forms”) refers to the small number of modern animals that originated during this epoch. oligocene climates appear to have been temperate.
