Geologists determined the division of the geologic time scale through the study of rock layers and the fossils contained within them. By examining the different types of fossils and their distribution in the rock record, geologists were able to identify distinct time periods based on changes in the Earth's environment and the evolution of life forms. This process of relative dating helped establish the framework for the geologic time scale.
Epoch
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.
The shortest division in the geologic time scale is an Epoch. Epochs are subdivisions of a period and are typically tens of millions of years long.
