|Subdivision of the Neogene Period
according to the IUGS, as of July 2009.
The Messinian is in the geologic timescale the last age or uppermost stage of the Miocene. It spans the time between 7.246 ± 0.005 Ma and 5.332 ± 0.005 Ma (million years ago). It follows the Tortonian and is followed by the Zanclean, the first age of the Pliocene.
The Messinian overlaps the Turolian European Land Mammal Mega Zone (more precise MN 12 and 13) and the Pontian Central European Paratethys stage. It also overlaps the late Huayquerian and early Montehermosan South American Land Mammal Ages, and falls inside the more extensive Hemphillian North American Land Mammal Age.
The base of the Messinian is at the first appearance of the planktonic foram species Globorotalia conomiozea and is stratigraphically in the middle of magnetic chronozone C3Br.1r. The GSSP for the Messinian is located in a section at Oued Akrech, near the Moroccan capital Rabat.1
The top of the Messinian (the base of the Zanclean stage and Pliocene series) lies with the top of magnetic chronozone Cr3 (about 100,000 years before the Thvera normal subchronozone C3n.4n). The base is also close to the extinction level of the calcareous nanoplankton species Triquetrorhabdulus rugosus (the base of biozone CN10b) and the first appearance of nannoplankton Ceratolithus acutus.
