The Upper Cretaceous – Lower Tertiary succession exposed at Saint Paul and Sudr El-Hitan around t he Gulf of Suez have been measured and studied in details using both macro- and microfossil assemblages. Saint Paul section was subdivided lithostratigraphically into the Galala Formation (Cenomanian – early Middle Turonian), the Wata Formation (late Middle – Late Turonian), the Matulla Formation (Coniacian – Santonian), the Sudr Chalk (Campanian earliest Paleocene), the Esna Formation (Paleocene – earliest Eocene) and the Thebes Formation (Early Eocene). In Sudr El-Hitan section, it has been subdivided lithostratigraphically into the Sudr Chalk (Campanian - Maastrichtian), the Esna Formation (Paleocene – earliest Eocene) and theThebes Formation (Early Eocene). Biostratigraphically; five ammonite zones, six bivalves, two gastropod, and two echinoids have been recognized in Saint Paul section. Sixteen planktic foraminiferal and fourteen nannoplanktons were proposed from the same section. In Sudr El-Hitan,
thirteen planktic and twelve nannoplanktons have been suggested. The integration between the proposed biozones as well as local and inter-regional correlation of the biozones has been discussed. The stage boundaries of the studied stratigraphic interval have been discussed by using the various macrofossil and microfossil groups.
