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 largest division of time on the geologic time scale is an eon. Eons are subdivided into eras, which are further divided into periods, epochs, and ages. The current eon, the Phanerozoic, began around 541 million years ago and is divided into the Paleozoic, Mesozoic, and Cenozoic eras.

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.
The third largest division of geologic time is an era. The eras are further divided into periods, epochs, and ages.
