True or False? During the Precambrian time what was the most natural event? What order do we order the eras?Geologic Time Scale. Today, the geologic time scale is divided into major chunks of time called eons. Eons may be further divided into smaller chunks called eras, and each era is divided into periods. Figure 12.1 shows you what the geologic time scale looks like. We now live in the Phanerozoic eon, the Cenozoic era, and the Quarternary period.The Cenozoic Era is also divided into seven epochs, which are the smallest units of time in the geologic time scale. An epoch is a unit of geologic time that further subdivides periods, narrowing ...
