Abstract
    The present paper presents the guide book of the excursion of the « Groupe d'Etude du Paleogene» in southern Aquitaine (4-6 september 2000), organized by the authors. Numerous Paleogene sections are discussed. Several of them were never described in detail previously: various sections on the Lespontes river at Saint-Lon-Ies-Mines (Middle and Upper Eocene), others on the road from Gan to Rebenacq (Paleocene-Ypresian), in the Gan area (Ypresian) and at Lahosse (Rupelian). Several classic sites are also presented and updated. Special attention has been given to the fIlling of the Saubrigues paleocanyon, with deposits ranging from Chattian to Langhian age. The stratigraphy of all studied levels is detailed with calcareous nannoplankton analyses, and for several sections, paleoecological data based on the analysis of fish otoliths and microbenthos (foraminifers, ostracods) are presented. This provides a series of southern Aquitaine reference localities for any complementary study. Moreover, these localities are well calibrated in time and exemplify the wide variety of facies that can be observed in the marine sedimentation realm of this region.
