Rupelian
33.9 – 27.82 Ma
Chronology

The Rupelian is, in the

Epoch/Series. It spans the time between 33.9 and 27.82 Ma. It is preceded by the Priabonian Stage (part of the Eocene) and is followed by the Chattian
Stage.

Name

The stage is named after the small river

André Hubert Dumont in 1850. The separation between the group and the stage was made in the second half of the 20th century, when stratigraphers saw the need to distinguish between lithostratigraphic and chronostratigraphic
names.

Stratigraphic definition

The base of the Rupelian Stage (which is also the base of the Oligocene Series) is at the

GSSP for the base of the Rupelian has been assigned in 1992 (Massignano, Italy). The transition with the Chattian has also been marked with a GSSP in August 2017 (Monte Conero, Italy).[5]

The top of the Rupelian Stage (the base of the Chattian) is at the extinction of the foram genus Chiloguembelina (which is also the base of foram biozone P21b).

The Rupelian overlaps the

Asian Land Mammal Age. It is also coeval with the only regionally used upper Aldingan and lower Janjukian stages of Australia, the upper Refugian and lower Zemorrian stages of California and the lower Kiscellian Paratethys
stage of Central and eastern Europe. Other regionally used alternatives include the Stampian, Tongrian, Latdorfian and Vicksburgian.
