Faunal stages are subdivisions of rock layers used primarily by paleontologists who study fossils rather than by geologists who study rock formations. Typically, a faunal stage will consist of a series of rocks that contain similar fossils.

The Miocene Epoch is a period of time that extends from about 23.03 to 5.332 million years before the present. As with other older geologic periods, the rock beds that define the start and end are well identified but the exact dates of the start and end of the period are uncertain.

Aquitanian is the first stage of the Miocene Epoch. It spans the time between 23.03 ± 0.05 Ma and 20.43 ± 0.05 Ma (million years ago). The Aquitanian Stage succeeds the Chattian age of the Oligocene Epoch and precedes the Burdigalian Stage.

Langhian is a stage of the middle Miocene epoch that spans the time between 15.97 ± 0.05 Ma and 13.65 ± 0.05 Ma (million years ago).

The Langhian stage was defined by M. F. Pareto in 1864, based on evidence from the Langhe area north of Ceva in northern Italy.
