Stratigraphic definition[edit]

The Aquitanian Stage was named after the Aquitaine region in France and was introduced in scientific literature by Swiss stratigrapher Karl Mayer-Eymar in 1858.

The base of the Aquitanian (also the base of the Miocene Series and the Neogene System) is defined as the place in the stratigraphic column at the first appearance of foram species Paragloborotalia kugleri, the extinction of calcareous nanoplankton species Reticulofenestra bisecta (which forms the base of nanoplankton biozone NN1), and the base of magnetic chronozone C6Cn.2n. The official GSSP for the Aquitanian Stage lies in the Lemme-Carrosio section near the small village of Carrosio (north of Genoa) in northern Italy.^[6]

The top of the Aquitanian Stage (the base of the Burdigalian) is at the first appearance of foram species Globigerinoides altiaperturus and the top of magnetic chronozone C6An.
