Epochs are defined on a global level, and their beginning and end are dated to specific points in time. Hominins first appear by around 6 million years ago, in the Miocene epoch, which ended about 5.3 million years ago. Our evolutionary path takes us through the Pliocene, the Pleistocene, and finally into the Holocene, starting about 12,000 ...Geologic Time Scale. Rise of civilization and agriculture.

Series (stratigraphy) Series are subdivisions of rock layers based on the age of the rock and formally defined by international conventions of the geological timescale. A series is therefore a sequence of strata defining a chronostratigraphic unit. Series are subdivisions of systems and are themselves divided into stages .The geologic time scale is often shown with illustrations of how life on Earth has changed.

To make geologic time easier to comprehend, geologists divided the 4.6 billion years of Earth’s history into units of time called eons. Then they further divided the eons into two or more eras, eras into two or more periods, periods into two or more epochs, and epochs into two or more ages. These units are called geochronologic units, (geo ...Neogene Period, the second of three divisions of the Cenozoic Era.The Neogene Period encompasses the interval between 23 million and 2.6 million years ago and includes the Miocene (23 million to 5.3 million years ago) and the Pliocene (5.3 million to 2.6 million years ago) epochs.
