The GSSP method defines stage bases, and, where proximate, equates them to the bases of larger chronostratigraphic units. The Phanerozoic and its subdivisions above the stage level thus are only successively larger “pigeonholes” within which to bin stages. This reductionism trivializes chronostratigraphic boundaries larger than stage boundaries. A single set of standard global stages is an unworkable abstraction that should be abandoned because no stage can be correlated globally because of facies changes, taphonomic biases, and/or provincialism. Stratigraphers should return to a top-down chronostratigraphy that defines chronostratigraphic units larger than stages by significant natural events that can be correlated globally.
