[4] The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France.

The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite Paradeshayesites oglanlensis.

[citation needed] The Barremian falls in the Gallic epoch, a subdivision of the Cretaceous that is no longer used by the ICS.

It overlaps the lower part of the Urgonian [pl] stage, which is sometimes used in western European stratigraphy.

In North America, the late Coahulian and the early Comanchean correspond to the Barremian.
