Abstract This study investigates ostracod faunas from the well-preserved Paleocene to lower Eocene sedimentary succession at Wadi Tarfa, North Eastern Desert, Egypt. A total of 22 species and subspecies across 16 genera 8 families were identified 57 samples. Three zones identified: Doricythereis jordanica Zone, Cytheropteron toshkaensis Phalcocythere horraensis based on stratigraphic distribution fauna. However, correlations with other sections revealed inconsistencies in first last...
Abstract The Late Cretaceous was a time of high eustatic sea level that enabled extensive epicontinental seaways and carbonate platforms across the Tethyan Realm, providing favorable habitats for oyster communities to flourish. This study focuses on Campanian oysters from North Eastern Desert Egypt regarding taxonomy, palaeoecology, palaeobiogeography. Three species, Nicaisolopha nicaisei (Coquand, 1862), Pycnodonte ( Phygraea ) vesicularis (Lamarck, 1806), Ambigostrea bretoni (Thomas Peron,...
In the Batna Mountains, Cenomanian Marnes de Smail Formation yield fossiliferous deposits mostly dominated by bivalves. Thirty-five bivalve species were identified, belonging to nine orders, 19 families and 26 genera. Five of them are mentioned for first time from study area (i.e., Nucula ? cf. margaritifera Douvillé, Barbatia (Barbatia) aegyptiaca Fourtau, Cucullaea trigona Seguenza, Arctica inornata d’Orbigny, A. cordata Sharpe). Their distribution provided interesting insights on marine...
Thirty-six species of bivalves, belonging to 22 genera, representative 16 orders, are systematically described from five upper Campanian-lower Eocene sections in the Kharga Oasis. Stratigraphically, 15 were recorded Palaeocene, 8 lower Eocene, Maastrichtian, 3 Campanian, 1 Campanian-Maastrichtian and Maastrichtian-Palaeocene. The paleobiogeographic distribution bivalves reveals high degree marine connection between South Tethyan province West Africa, Middle East, southern Europe, America...
The Maastrichtian sedimentary succession in the Abu Monqar-west Dakhla stretch yields rare cephalopod content. Six cephalopods, including three nautiloids and ammonoids, are described detail identified. Two new species of erected from study area; these Angulithes monqarensis nov. sp. Anglonautilus hewaidyi ammonoid Sphenodiscus lobatus (Tuomey) is firstly recorded rocks Egypt. Paleobiogeographically, Pachydiscus (P.) neubergicus has a wide geographic distribution within Tethyan Boreal...
