Article History

Hauterivian Stage, third of six main divisions (in ascending order) of the Lower Cretaceous Series, representing rocks deposited worldwide during the Hauterivian Age, which occurred 132.9 million to 129.4 million years ago during the Cretaceous Period. Rocks of the Hauterivian Stage overlie those of the Valanginian Stage and underlie rocks of the Barremian Stage.

The name of the stage is derived from the village of Hauterive in Switzerland, the surrounding area of which serves as the classic type district for rocks of this age. The Hauterivian Stage is represented in northern continental Europe by part of the thick Hils clay, whereas in Britain it includes the middle part of the Wealden sandstones and clays. The base of the stage is defined by the first appearance of the ammonite Acanthodiscus radiatus and related species, which are used as index fossils. The Hauterivian has been divided into several shorter spans of time called biozones. One of these is characterized by the planktonic foraminiferan Caucasella hoterivica, which is another index fossil for rocks of this age.
