The Cenomanian-Turonian of the Saharan Atlas (Algeria)

Carnets de Géologie, 2007
Through the correlation of a ten of sections from platform to basin we suggest that the Cenomanian-Turonian Boundary Event and the deposition of black shales are at least in part linked to morphologic changes due to shallow-water carbonate production during a rise in relative sea-level, at first slow, faster later.

Early Turonian ammonites from Goulmima, southern Morocco

, 2016
In recent years, large numbers of Early Turonian ammonites from Morocco have found their way onto the open market. They come from the Cretaceous escarpment to the north of Goulmima, in the province of El Rachidia, southern Morocco. A section measured northeast of the village of Asfla sets the ammonites in stratigraphic context. The fauna belongs to the
