The stage is the fundamental chronostratigraphic unit.

Being chronostratigraphic units, stages represent the body of rocks formed during a given interval of geologic time. The corresponding geochronologic units are called ages.

Stages/ages are formally defined following the indications of the ICS (International Commission on Stratigraphy). More specifically, stages/ages are defined by the GSSP of their base, their top being defined by the GSSP of the overlying stage/age.

A list of stages/ages may be found here.
