The Late Cretaceous is the last geochronologic subepoch of the Cretaceous, starting with the Cenomanian age (at the transition from the Early Cretaceous subepoch) and ending with the Maastrichtian age (at the transition to the Plaeocene subepoch). It is subdivided in six ages (Cenomanian, Turonian, Coniacian, Santonian, Campanian and Maastrichtian).
