The Sarvak Formation is a carbonate sequence of Late Albian-Early Turonian age in Zagros Basin in Iran. In this investigation, the Sarvak Formation at the Pyun Anticline section (Izeh Zone) has been studied. It consists of 797 m thick limestone which overlies the Kazhdumi Formation conformably and underlies the Gurpi Formation unconformably at the Pyun Anticline. A very rich fossil association (85 genera and 132 species) characterizes the Pyun section. Based on the stratigraphic distribution of diagnosed foraminifera, five biozones are established: 1, Muricohedbergella-Globigerinelloides sp. assemblage zone (Late Albian); 2, Praealveolina iberica-Chrysalidina gradata interval zone (Early Cenomanian); 3, Chrysalidina gradata-Cisalveolina fraasi (fallax) and C. lehneri interval zone (Middle Cenomanian); 4, C. fraasi (fallax) and C. lehneri-Praetaberina bingistani assemblage zone (Late Cenomanian); 5, Nezzazatinella picardi-Mangashtia-Dicyclina assemblage zone (Early Turonian). Based on the petrographic and sedimentological analyses, some 13 carbonate microfacies were identified. The investigated microfacies confirm a ramp-type paleoenvironment. These microfacies, from distal to proximal environments, consist of: MF1:

“…The biocorrelation between the proposed foraminiferal biozones and those from other parts in Egypt is shown in Table 1. Equivalents and age: In Egypt, this zone is comparable to the lower part of the Thomasinella fragmentaria Zone of Ansary et al (1962) and Shahin (2007), the base of the Daxia cenomana Zone of Kora et al (1994), the lower part of the Thomasinella aegyptia Zone of Galal and Nafae (2007), the lower part of the Daxia cenomana-Cribrostomoides sinaica Zone of Abd-Elshafy et al (2002), the base of Daxia cenomana-Merlingina cretacea Zone of Shahin and El Baz (2013a) and the middle and upper parts of the Daxia cenomana-Mayncina d'orbignyi Zone of El Baz and Khalil (2019). On the other side, the comparable planktonic foraminiferal biozones may include the lower part of the Rotalipora brotzeni Zone of Caron (1985), Lipson-Benitah, Almogi-Labin, and Sass (1997), Premoli Silva and Sliter (1999) and Cetean, Bãlc, Kaminski, and Filipescu (2008).…”

The present study concentrates on the foraminiferal and ostracod assemblages recorded from the subsurface Galala Formation in the northern part of the Gulf of Suez, Egypt. This investigation yielded 37 foraminiferal species (belonging to 26 genera, 10 superfamilies, and 14 families) and 25 ostracod species (belonging to 14 genera, 6 families, and 2 superfamilies). The foraminiferal assemblage is characterized by the dominance of typical Cenomanian agglutinated species with some planktonic species. The integration between benthic and planktonic foraminiferal species has led to the recognition of five proposed local biozones namely: Flabellammina alexanderi-Daxia cenomana Zone, Thomasinella fragmentaria Zone, Ismailia neumannae Zone, Nezzazata simplex-Trochospira avnemelichi Zone, and Hedbergella delrioensis-Praeglobotruncana delrioensis Zone. On the other hand, the stratigraphic distribution of the recorded ostracods resulted in the identification of four local biozones, involving Glenocythere reticulata Zone, Veeniacythereis streblolophata Zone, Spinoleberis yotvataensis Zone, and Cytherella-Ovocytheridea Zone. The recorded foraminifera are classified into five morphogroups and submorphogroups. Based on these morphogroups and other palaeoecological factors, five ecozones covering the Cenomanian are also distinguished. The palaeobiogeographical outline of the studied ostracod assemblages was carried out with the assistance of multivariate analyses (principal component analysis and Q-mode cluster analysis). The results point out that, there are two distinguished groups; one of them represents the South Tethyan Province (STP), including Morocco, Algeria, Tunisia, and Egypt. The second group represents the Middle East Province (MEP), including Oman, Lebanon, Saudi Arabia, Kuwait, and Iran. The strong affinity between the two provinces indicates a direct communication along the Southern Tethyan margin during the Cenomanian and enhanced marine faunal exchange.
