OLIGOCENE Meaning and
Definition
-
Oligocene is a term used in the field of geology and paleontology to refer to a specific epoch in the geological timescale. It is a division of the Cenozoic era and is characterized as the third and latest epoch of the Paleogene period, lasting from approximately 33.9 to 23.03 million years ago.
The name "oligocene" is derived from the Greek words "oligos" meaning "few" and "ceno" meaning "new," suggesting that during this epoch, the number of distinctive species or genera decreased compared to previous periods. It is considered an important period in Earth's history, marking a transitional phase between the warmer and more tropical conditions of the preceding Eocene epoch and the cooler climates of the upcoming Miocene epoch.
During the Oligocene, many significant geological and biological events occurred. There was a gradual global cooling trend, leading to the formation of ice caps on Antarctica and a decline in sea levels. The diversification of grasses and the development of more open environments also took place, influencing the evolution of mammals, including the emergence of early forms of modern primates.
Additionally, the Oligocene represents a time of notable volcanic activity and tectonic movements, resulting in the formation of various mountain ranges and geological formations.
In summary, the Oligocene epoch was a crucial period in Earth's history marked by both geological and biological changes, setting the stage for the subsequent climate shifts and evolutionary developments of the Miocene epoch.
