Abstract

Following votes by the Hauterivian Working Group, the Cretaceous Subcommission and the International Commission on Stratigraphy, in December 2019 the Executive Committee of the International Union of Geological Sciences unanimously approved the proposal that the Global Stratotype Section and Point (GSSP) for the base of the Hauterivian Stage of the Lower Cretaceous be placed at the base of bed n° 189 of the La Charce section, Drôme, southeast France (Vocontian Basin). This level is marked by the first appearance of the ammonite genus Acanthodiscus, which defines the base of the Acanthodiscus radiatus ammonite Zone. Complementary data include 13 ammonite and nannofossil events, and magnetostratigraphic and carbon isotope events.
