Stratigraphic definition

The name Burdigalian comes from Burdigala, the Latin name for the city of Bordeaux, France. The Burdigalian Stage was introduced in scientific literature by Charles Depéret in 1892.

The base of the Burdigalian is at the first appearance of foram species Globigerinoides altiaperturus and the top of magnetic chronozone C6An. As of 2016, an official GSSP for the Burdigalian had not yet been assigned.

The top of the Burdigalian (the base of the Langhian) is defined by the first appearance of foram species Praeorbulina glomerosa and is also coeval with the top of magnetic chronozone C5Cn.1n.
