Abstract The present thesis deals with palaeontological and stratigraphical Studies on some macrofossils collected from six upper Cretaceous outcrops exposed at southern Wadi Qena and neighbouring areas Eastern Desert of Egypt . It is focused mainly on bivalves gastropods and ammonites ,presenting a detailed systematic work as well as biometrical analyses of certain oysters. Ths study present also a detailed litho-and biostratigraphical classification for the upper cretaceous sequence of the measured sections. Lithostratigraphically the fossiliferous Upper cretaceous sequence exposed in the study area iis subdivided from top to into: Dakhla formation,Duwi formation,Quseir formation,Umm O meiyid formation,and Galala formation. The Studied sequence is unconformably overlying the pre-Cenomanian non- marine sandstone succession of the Wadi Qena formation and terminated by the Tertiary marly part of the Dakhala formation correlation charts for the recognized rock units are constructed. |
