Abstract
In accordance with the recommendations of the International Commission on Stratigraphy (ICS), the leading
candidate for the Global Boundary Stratotype Section and Point (GSSP) of the base of the Bathonian Stage
is located in the Ravin du B¯s (Bas Auran area, SE France). This section was formally proposed as candidate nineteen
years ago. A second potential candidate section is located in the Cabo Mondego area (Portugal). This Portuguese
section, however, has not been formally proposed as a candidate for the Bathonian basal boundary stratotype.
The formal selection and proposal of a GSSP for the Bathonian Stage is the responsibility of the Bathonian Working
Group (BtWG) and is expected by September 2007. In accordance with the procedures to ratify GSSPs, a formal ballot
on the selection and proposal of a GSSP for the Bathonian Stage, by post or email, by all members of the BtWG is
the responsibility of the convenor and the International Subcommission on Jurassic Stratigraphy Executive, and will be
carried out within this time scale.
