Aquitanian
Aquitanian
1. The earliest age in the Miocene Epoch, preceded by the Chattian (Oligocene), followed by the Burdigalian, and with a lower boundary set at 23.3 Ma ( Harland et al., 1989).
2. The name of the corresponding European stage, which is roughly contemporaneous with the upper Zemorrian and lower Saucesian (N. America), parts of the Otaian (New Zealand), and the upper Janjukian and lower Longfordian (Australia). The stratotype is in the Aquitanian Basin, France. The Aquitanian is itself characterized by the appearance of the planktonic foraminiferid Globigerinoides primordia.
