Chronology

The Messinian is in the

Ma and 5.333 ± 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

North American Land Mammal Age
.

During the Messinian, around 6 million years ago, the Messinian salinity crisis took place, which brought about repeated desiccations of the Mediterranean Sea.

The Messinian was introduced by Swiss stratigrapher Karl Mayer-Eymar in 1867.[6] Its name comes from the Italian city of Messina on Sicily, where the Messinian evaporite deposit is of the same age.

The base of the Messinian is at the first appearance of the

foram species Globorotalia conomiozea and is stratigraphically in the middle of magnetic chronozone C3Br.1r. The Global Boundary Stratotype Section and Point for the Messinian is located in a section at Oued Akrech, near the Moroccan capital Rabat.[7]

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 top is also close to the

nanoplankton species Triquetrorhabdulus rugosus (the base of biozone CN10b) and the first appearance of nanoplankton Ceratolithus acutus.[citation needed

Ce nom est celui d'Etage messinien."
