An integrated biostratigraphic study by means of planktonic foraminifera and macrofauna has been developed for the Cenomanian-Turonian(C/T) transition in the Khanguet Esslougui section. Several important bioevents of ammonites are recorded in this section from older to younger (FOs of Calycoceras cenomanense, Vascoceras cauvini and Pseudaspidoceras pseudonodosoides) and planktic foraminifera (LO of Rotalipora cushmani, FOs of Witheinella archaeocretacea and Helvetoglobotruncana helvetica). The base of the studied section is characterized by the black shale which occurs within the upper part of the Rotalipora cushmani Zone and matches with the Oceanic Anoxic Event 2 (OAE 2). The Cenomanian/Turonian boundary is detected within the Witheinella archaeocretacea biozone (PRZ) above directly the ammonite zone of Pseudaspidoceras pseudonodosoides.
