Burdigalian
1. An age in the Early Miocene, preceded by the Aquitanian and followed by the Langhian.

2. The name of the corresponding European stage, dated radiometrically as about 21.5–16.3 Ma ago, which is roughly contemporaneous with the upper Saucesian (N. America), upper Otaian and Altonian (New Zealand), and the upper Longfordian and Batesfordian (Australia). The type section is at Le Coquillat, France. Mammals, including elephants, are important in the stratigraphic definition of this stage.

Burdigalian A stage of the early Miocene, about 19–14.4 Ma ago, underlain by the Aquitanian and overlain by the Langhian.

Burdigalian A stage of the early Miocene, about 20.43–15.97 Ma ago, underlain by the Aquitanian and overlain by the Langhian. Mammals, including elephants, are important in the stratigraphic definition of this stage.
