The comparative study of the vertical repartition of the main benthic Foraminifera and Algae conducts to propose four foraminiferal biozones in the upper Albian and the lower Cenomanian. The stratigraphie position of these biozones is defined with respect to levels containing Ammonite zones known in the Pyrenees. The proposed scale permits to state precisely the age of different organisms living in the shelf-domain.L'étude comparative de la répartition verticale des principaux Foraminifères benthiques et Algues conduit à la proposition de quatre biozones de Foraminifères étagées sur l' Albien supérieur et le Cénomanien inférieur. La position stratigraphique de ces dernières est définie par rapport à des niveaux à Ammonites de zone connues ...
