“…The base of the Eg UK-9 sequence is defined by the SB Ma-8 sequence boundary. It correlates well with the Campanian/Maastrichtian tectonic event (El Ayyat & Obaidalla, 2013). In the St. Anthony area the Campanian/ Maastrichtian stage boundary is represented by an important unconformable contact due to the absences of CC24 and CC25a nannofossil zones (Scheibner et al, 2001).…”

“…SB Ca-8 was recorded by various authors in Egypt based on obvious facies and paleontological changes (Farouk and Faris, 2012). It corresponds to a major tectonic event marked by uplifting, marine regression and intensive erosion across the Santonian/ Campanian boundary in the north Eastern Desert (El Ayyat and Obaidalla, 2013). This sequence varies in thickness from 18 to 40 m (Figs.…”

“…The most plausible explanation of the absence of index taxa Abathomphalus mayaroensis is the bathymetry, because this species is bathypelagic, thus absent in shallower areas of the basin (Farouk, 2014;Kędzierski et al, 2015). Another argument is the fact that A. mayaroensis is seldom found in tropical areas (Premoli- Silva and Verga, 2004;Abdallah and Obaidalla, 2013).…”

The Sirte Basin is located in the north-central part of Libya (Fig. 1). It is a basin characterized by a series of platforms and deep troughs containing several oil and gas fields. Depositional history of the Sirte Basin started in the Early Cretaceous time, which has been related to the tectonic evolution of the North African passive continental margin. The history of the Sirte Basin had been spanning the Cretaceous and Palaeogene times. It had been influenced by several marine transgressions and several rifting phases induced by the deformation of the North African continental margin. The relative sea-level changes and the tectonics might have greatly influenced the accomodation space, especially over the Western Sirte Basin (WSB) during the Palaeogene.Because of the numerous oil and gas fields, the geological history of the WSB was the subject of numerous stud-

“…These outcrops are represented by Sudr Formation at Northern and Southern Galala Plateaus, north Eastern Desert [4]. The Sudr Formation underwent extensive literature concerning the stratigraphic aspects [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], foraminiferal content [3,[20][21][22][23][24][25][26][27][28], and calcareous nannoplankton content [29][30][31]. So far, the macrofaunal content of Sudr Formation in north Eastern Desert received no attention.…”

The Upper Cretaceous deposits are widely distributed and well exposed in northern Egypt. Important upper Campanian-Maastrichtian carbonate deposits outcrop at the Northern and Southern Galala Plateaus, north Eastern Desert, represented by Sudr Formation. Sudr Formation is lithologically investigated, sampled, and the included fauna are collected for taxonomic and paleobiogeographic studies. Four gastropod species, belonging to three genera and three families, as well as twelve bivalve species, representative of twelve genera and nine families, are identified. Two gastropod species; Cerithium buddha Noetling, Potamides temalacaensis Perrilliat et al., and four bivalve species; Gryphaeostrea canaliculata (Sowerby), Venilicardia truncata (Sowerby), Calva (Egelicalva) buttensis (Anderson), Lyriochlamys dentata (Nilsson), are recorded for the first time from the Upper Cretaceous deposits of Egypt. The microfacies analysis of the carbonates of Sudr Formation revealed four distinct microfacies types, each with characteristic bioclasts and textural features. These microfacies types suggest open-marine, high-energy shallow subtidal shoal to low-energy deep subtidal environments. The paleobiogeography of the recorded bivalve taxa is highlighted, revealing two endemic species to Egypt; Nucula chargensis Quaas and Meretrix rohlfsi (Quaas). On the other hand, the other identified bivalve species show wide distribution over a broad geographical
