Eon, Era, Period, Epoch (from largest to smallest)
Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.
Phanerozoic is the eon which geologic time scale means visable life.
Eon is the broadest division on the geologic time scale, representing the longest time span. Eons are further divided into eras, which are then subdivided into periods, epochs, and ages.
Epoch
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
