Campanian in the geochronological sense - the fifth century of the Late Cretaceous of the Mesozoic Era, lasting about 11.5 million years (from 83.6 ± 0.2 to 72.1 ± 0.2 to million years). The Campan is younger than the Santon and older than the Maastrichtian in a chronostratigraphic sense - the fifth tier of the Upper Cretaceous of the Mesozoic Eratemia, higher than the Santon and lower than the Maastrichtian. The lower border of the Santon is not yet approved. The border is based on the extinction of the daylily Marsupites testudinarius (Schlotheim, 1820). The name comes from the Latin name of the French land of Champagne - Campania.
