Abstract

Calcareous nannofossils from the mid-Cretaceous (Barremian to Coniacian) were studied from three sections near Timezguida Allal, Ameskhoud, and El Ma in Western Morocco. Ranges of 47 previously described coccolith species are given. A zonation is tentatively proposed and compared with existing coccolith zonations proposed for France, Alabama and Kansas. The nannoflora was compared with material from several D.S.D.P. cores in the eastern Atlantic Ocean.

Des nannofossils calcaires du Crétacé moyen (Barrémien du Coniacien) ont etés étudiés dans trois profiles prés de Timezguida Allal, Ameskhoud, et El Ma en Maroc occidental. Des rangées de 47 espèces des coccolithes déja decrites ont données. Une zonation est proposée tentativement et comparée avec du materieux du plusieurs carottes D.S.D.P. dans l'est de l'ocean Atlantique.
