List of geochronologic names

List of geochronologic names

This is a list of official and inofficial names for time spans in the geologic timescale and units of chronostratigraphy. Since many of the smallest subdivisions of the geologic timescale were in the past defined on regional lithostratigraphic units or local biozones, periods, there are currently many alternative names that overlap. The body concerned with standardizing the names of geochronologic units is the International Commission on Stratigraphy (ICS). In 2008 however, even though the Phanerozoic eon is almost completely divided in internationally recognizable units, local subdivisions are often still preferred over the international ones.
