Abstract
In Middle-east, the albo-cenomanian comprises a prolific lithostratigraphic nomenclature. In-house studies on subsurface and outcrops sections lead Total biostratigraphers to use foraminifers charts for datings and paleoenvironments definition. Calibration on Ammonites zones is possible in the Late Albian-Early Cenomanian and Mid Cenomanian of Oman. Further work of biostratigraphers could focus on a characterization of the "top Natih" or "top Mishrif" carbonate platform with foraminiferal assemblages located at formation top and a research of new sections at platform-basin transition. This will help in the evaluation of the degree of truncation of the “Mishrif/Natih” formations below the turonian-coniacian unconformity.
