N°56 (NLD) Rev. Palaeobot. Palynol. N°56 Dinoflagellate cysts from the Cretaceous-Tertiary boundary sequence of El Kef (Northwest Tunisia). Les kystes de dinoflagellés de la limite Crétacé-Tertiaire du Kef. Rich dinoflagellate cysts associations have been studied from the Cretaceous/Tertiary boundary interval of the El Haria section near El Kef, northwest Tunisia. No sharp qualitative changes in the dinoflagellate cysts associations coincide with that boundary. A latest Maastrichtian-earliest Danian (unnamed)interval and an early Danian Danea californica biozone is recognized. The biostratigraphic value of the first appearence datum of Danea californica for discriminating between latest Maastrichtian and the earliest Danian associations is supported.
