Understanding the Post-Oligocene: A Geological Time Period of Significant Change
The term "Post-oligocene" refers to the geological time period that follows the Oligocene epoch, which spanned from approximately 34 million to 23 million years ago. The Oligocene was a time of significant global cooling and the formation of the Antarctic ice sheet, and it marked the beginning of the modern glacial cycle.
The Post-oligocene is not a formally recognized geological epoch, but rather a general term used to describe the period of time since the Oligocene. It includes the Miocene epoch, which spanned from approximately 23 million to 5.3 million years ago, as well as the Pliocene epoch, which began around 5.3 million years ago and continues to the present day.
During the Post-oligocene, the Earth's climate continued to cool, and the ice sheets expanded and contracted in response to changes in the Earth's orbit and other factors. The Post-oligocene also saw the emergence of early human populations and the development of modern ecosystems.
