Units of the international
chronostratigraphic scale with
estimated numerical ages.
Colors are according to the
Commission for the Geological
Map of the World.
Subdivisions of the Phanerozoic (~541 Ma to Present) and
the base of the Ediacaran are
defined by a basal Global
Boundary Stratotype Section
and Point (GSSP
), whereas
the Precambrian units are
formally subdivided by absolute
age (Global Standard
Stratigraphic Age, GSSA).
Stratigraphic information and
details on international and
regional geologic units can be
found on the websites of the
Geologic TimeScale Foundation
