Chronology

The Aquitanian is, in the

Ma and 20.43 ± 0.05 Ma (million years ago) during the Early Miocene. It was a dry, cooling period.[5] The Aquitanian succeeds the Chattian (the youngest age of the Oligocene) and precedes the Burdigalian
.

The Aquitanian Age overlaps with the

Waitakian
Ages from various regional timescales.

Stratigraphic definition

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

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

Globigerinoides altiaperturus
and the top of magnetic chronozone C6An.
