Ma and 15.97 ± 0.05 Ma (million years ago). Preceded by the Aquitanian, the Burdigalian was the first and longest warming period of the Miocene[4] and is succeeded by the Langhian
.

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.

Possible human evolutionary ancestors such as Victoriapithecus evolved during this time interval.
