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.
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
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.
Usually, they represent periods between extinction events, where a particular type of lifeform was dominant.
The four large sections on the geologic time scale are eons, eras, periods, and epochs. Each of these divisions represents a different scale of time with eons being the largest and epochs being the smallest.
geologic time scale
The basic units of the geologic time scale eras and periods.
Eras and periods on the geologic time scale are often named based on significant geological events, key fossil groups, or regional stratigraphy that characterize that time interval. For example, the Triassic Period is named after the three distinct rock layers found in Germany. The Cretaceous Period is named after the Latin word "creta," meaning chalk, due to the abundant chalk deposits from this time.
By eons, eras, epochs, and periods.
