It is a subdivision of a geological period, and the word is capitalized when employed in a formal sense (e.g., Pleistocene Epoch). Additional distinctions can be made by appending relative time terms, such as early, middle, andGeologists have split its history into large blocs of time called eons, which are further subdivided into eras. Those in turn are made up of smaller units called periods. Finally, the little divisions within a period are known as epochs. So right now, we're living in the Quaternary period of the Cenozoic era, which is part of the Phanerozoic eon.
