Abstract
The mari formations, Cenomanian in age, from the Alpes Maritimes have given up many planktonic Foraminifera (Globotruncanidae). Two sections, the first one in the south of "Col de Braus", the second in the "Vallée de l'Esteron", have been more particularly studied. In spite of a variation of facies, these sections allow us to point out some assemblage zones of Globotruncanidae, characteristic of the different levels belonging to Cenomanian. This biozonation may be put in correlation with that of B. Porthault in the "domaine vocontien".
