Lyropectcn Gigantopectcn the is Pacific Atlantic equivalent of the and Mediterranean From the stratigraphical point of view the identifications of these important fossils of the Pectinidae confirm the Miocene age of the Guadeloupe outcrops and show that the beds: ma, mb and mc of A de Reynal could belong to the Burdigalian, for some parts, and chiefly to the middle Miocene (Helvetian I, while the beds rnd represent the upper Miocene The other lamellibranchs and gastropods of this island will be studied later INTRODUCTION Ces levers ont ete trouves par A de Reynal au cours de ses fossiles de cartes sur l'etablissement Geol Fr ) II de a la de Tile carte resume la la Grande-Terre, Guadeloupe, geologique au 1/50.000 (1961, pour Carte stratigraphie des terrains tertiaires de coupe suivante (1961, pp 10-14) ma: Calcaires de base, calcaires subrecifaux de 80 metres d'epaisseur maximum, ocres, impurs, tres heterogenes, avec de nombreux moules internes de Gasteropodes, des Coraux, des Pectinides, des Algues cette ile dans la Calcaires et des Foraminiferes; mb: Sables et conglomerats marine a elements eruptijs, niveau-repnv interessant de un a sept dimensions moin variables m suivant d'epaisseur avec des conglomerats de les gisements, ou de sable plus ou grossier avec des moules internes de Gasteropodes, de Cardium, une grande quantite de Pecten, et de Foraminiferes correspond au "tuf des Abymes" de L Barrabe (1934b) Ce niveau Bulletin 245 472 mc: Calcaires environ, Algues et debris volcaniques, de 30 in depaisseur prmcipalement constitues par des Algues, LithoLithophyllum, des Polvpiers, et la meme faune mala
