| Abstract: | Gyrogonites of charophytes from two localities of the Oudiksou syncline (Middle Atlas, Morocco) are studied. The Irbzer formation in the Achlouj-2 site yielded charophytes (Feistiella oblonga, F. globosa, Strobilochara apiculata, S. diademata) that suggest a Campanian-Maastrichtian age; this result is consistent with all previously published biochronological studies. The overlying Bekrit-Timahdit formation, supposed to be Thanetian to Lutetian in age, without paleontological evidence, yielded charophytes in the Saf locality (Peckichara cf. llobregatensis, Feistiella sp. 1, Maedleriella sp.). This association indicates a Paleocene age for the middle member of this formation. |
