“…The last occurrence of R. cushmani is correlated with the uppermost Cenomanian, which is equivalent to the basal horizon of the OAE2 interval ( Fig. 2c) [19][20][21][22][23] . The first occurrence of the calcareous nannofossil marker species Quadrum gartneri Prins and Perch-Nielsen, which occurs at the base of the Turonian and the upper part or just above the OAE2 interval ( Fig.…”

“…Although the total organic carbon (TOC) content of both strata ranged from 0.5 to 1.5%, most of the organic matter is derived from terrestrial plants 11,17 . Mean sedimentation rates across the OAE2 intervals were estimated to be 30.5-31.9 cm ky − 1 in the GVS and 14.8-15.5 cm ky − 1 in the YG, which is several tens to hundreds of times greater than the hemipelagic and pelagic sediments that accumulated along the passive continental margin of the Atlantic Ocean and the Tethyan Sea 19,20 .…”

“…A detailed bio-and carbon isotope-stratigraphic framework across the OAE2 interval has been determined for Pueblo (USA), Eastbourne (England), Tarfaya (Morocco), Wadi Bahloul (Tunisia), Provence (France) and Gubbio (Italy) [19][20][21][22][23] . These studies have revealed a detailed stratigraphic range of age-diagnostic marker species in macro-and microfossils across OAE2.…”

“…2b). The first occurrence of M. schneegansi is thus placed at the uppermost horizon of the OAE2 interval 22,23 and that of H. helvetica at the uppermost part, or just above the OAE2 interval [19][20][21][22][23] in the Tethyan realms. Consequently, both bio-events are correlated with the lower Turonian.…”

The stratigraphic distribution of the different faunal groups of the upper Cenomanian–lower Turonian deposits in the north Eastern Desert, Egypt, is investigated. Variations in species richness, faunal diversity, extinction and origination rates before, during, and after the globally known Oceanic Anoxic Event (OAE) 2 are documented. The OAE2 interval is constrained by the first occurrence of the marker ammonite species Vascoceras cauvini and the last occurrence of Vascoceras proprium, along with the positive δ13C excursions, previously identified from the Wadi El-Burga section. A prominent decline in species richness and diversity, high extinction rates, and low origination rates of the recorded macrofaunal elements are reported during the OAE2 interval. Such faunal bottleneck was attributed to the prevailing major palaeoclimatic and palaeoenvironmental perturbations during that time. Besides oceanic anoxia, changes in sea water palaeotemperature and sea level are discussed. It can be concluded that oceanic anoxia, warming, and /or transgressive episodes were the major driving mechanisms of the faunal crisis reported in the present work.
