A high-resolution stratigraphy has been developed for the interval encompassing the Cenomanian–Turonian boundary (CTBI), by means of several lithological, biological and geochemical events. This work entails the study of two sections selected on the base of the completeness of their sedimentary record and their contrasting paleogeographical setting: (1) The Rock Canyon Anticline section...

On the northern side of the Central High Atlas, new lithological and biostratigraphical data, especially realized in the Naour syncline, allow us to precise the Cenomanian-Turonian boundary. We recognized in that syncline an apparently complete series, the Ben Cherrou series, that represent the Upper Cenomanian-Turonian interval. We recommend it as the referring section of the Ben Cherrou...
