Ghazalat-1 well, 6b (Cretaceous of Egypt)

Where: Western Desert, Egypt (29.0° N, 29.0° E: paleocoordinates 8.7° N, 23.8° E)

• coordinate estimated from map

When: Bahariya Formation, Early/Lower Cenomanian (99.6 - 93.5 Ma)

Environment/lithology: terrestrial; lithified, argillaceous sandstone and lithified, argillaceous shale

• Composed of sandstones and variegated shales, it conformably overlies the Kharita Formation and underlies the Abu Roash Formation. An early Cenomanian age was given to the Bahariya Formation (Schlumberger, 1984; Sultan, 1987; Bassiouni et al., 1992; EI-Shamma and Arafa, 1992; Abdel-Kireem et al., 1993). However, E1-Beialy (1994a,b) assigned a middle-late Albian to early Cenomanian age to the Bahariya Formation in the subsurface of the north Western Desert.

Size class: microfossils

Preservation: soft parts, original sporopollenin
