“…Genus Ramulina Jones, 1875 Ramulina shreifae sp. nov. (Plate 1, Figure 20) 2023 Ramulina pseudoaculata (Olsson)-Shreif et al [46] , p. 115, Plate 6, Figure 8. [45] ).…”

“…Type locality and sample no. : El Guss Abu Said, Western Desert, Egypt, samples 1, 2 (common), (after Shreif et al [46] ).…”

“…The paleogeographic maps recorded by many authors [47][48][49][50] show the Tethyan realm had been connected with the Atlantic Ocean from the west to the Indo-Pacific Ocean to the east, via the Mediterranean Sea, crossing the Middle East region during the Paleogene time (Table 5). [46] ).…”

“…Anan [30] noted that the probable environment of northern Egypt is outer neritic-upper bathyal, while deeper in central Egypt, are deposited in the middle-outer neritic. Shreif et al [46] noted that the abrupt decrease in the P/B ratio at the top of the Esna Formation and the erosional surface at the top of the Esna Formation indicate progressive or stepwise shallowing of the shelf through the succession of El Guss Abu Said, Western Desert, Egypt, and during the late Paleocene-Early Eocene. Berggren & Aubert [52] considered the Lower Tertiary fauna of the Maqfi section, Western Desert of Egypt, and the northern part of Sinai Peninsula to be predominantly related to the "Midway-type fauna, MTF", middle-outer neritic environment (50-200 m).…”
