In the official timescale of the ICS, the Pliocene is subdivided into two stages. From youngest to oldest they are:
The Piacenzian is sometimes referred to as the Late Pliocene, whereas the Zanclean is referred to as the Early Pliocene.
In the system of North American Land Mammal Ages the Pliocene overlaps with two stages: the Blancan (4.75–1.806 Ma) and Hemphillian (9–4.75 Ma). In the system of South American Land Mammal Ages, the Pliocene overlaps with the Montehermosan (6.8-4.0 Ma), Chapadmalalan (4.0-3.0 Ma) and Uquian (3.0-1.2 Ma). In the Paratethys area (central Europe and parts of western Asia) the Pliocene contains the Dacian (roughly equal to the Zanclean) and Romanian (roughly equal to the Piacenzian and Gelasian together) stages. As usual in stratigraphy, there are many other regional and local subdivisions in use.
In England the Pliocene is divided into the following stages (old to young): Gedgravian, Waltonian, Pre-Ludhamian, Ludhamian, Thurnian, Bramertonian or Antian, Pre-Pastonian or Baventian, Pastonian and Beestonian. In the Netherlands the Pliocene is divided into these stages (old to young): Brunssumian C, Reuverian A, Reuverian B, Reuverian C, Praetiglian, Tiglian A, Tiglian B, Tiglian C1-4b, Tiglian C4c, Tiglian C5, Tiglian C6 and Eburonian. The exact correlations between these local stages and the ICS stages is still a matter of detail.
