The Geologic Time Scale is divided up by four major intervals. In order from Largest to smallest:
Eons are the largest time frame covering hundreds of millions of years.
Eons are divided into smaller time intervals known as Eras.
Eras are subdivided into Periods.
Periods are broken into finer subdivisions known as Epochs.
Geologic time scale
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
The presence or absence of fossils has been used to compare the relative ages of rocks around the world and to arrange sedimentary rocks into a geologic time scale. Eons are the largest intervals of the time scale and range from 540 to 2,050 million years in length
The geologic time scale shows the timing and relationship of events that have occurred throughout Earth's history.

A major scale is represented with intervals of whole steps between each note except for mi & fa, and ti & do.

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.

Four eons comprise Earth's geological time scale. Other time intervals of the Earth are eras, periods, and epochs.
The scale outlines the development of Earth and life on Earth.
they use major fossil records
All major scales use the same exact pattern of intervals.
