Cenomanian-Turonian ammonite successions in the Tinrhert Basin (Southeastern Algeria): Revision and new data

In the Tinrhert area, the biostratigraphic ammonite successions are subdivided into nine bio-events that are easily correlatable with the upper Cenomanian-lower Turonian standard zonation. The paleobiogeographic affinities of the recorded taxa characterize these ammonoid assemblages as part of the southern Tethyan Province during the early Late Cretaceous.
