Faddah-I well, Mingar-IX well, Sharib-IX well (P-S1, Hauterivian-Barremian) (Cretaceous to of Egypt)

Also known as Three boreholes from northern Western Desert (Egypt)

Where: Western Desert, Egypt (29.0° N, 29.0° E: paleocoordinates 7.2° N, 25.0° E)

When: Hauterivian to Hauterivian (132.9 - 125.0 Ma)

Environment/lithology: coastal; lithified sandstone

• Hauterivian-Barremian sediments suggest a general trend toward a more coastal to inner-shelf depositional environment. This may also be in- ferred from the high relative percentages of representatives of the genera Cribroperidinium, Cyclonephelium,Escharisphaeridiaand Systemato- phora.

Size class: microfossils

Preservation: soft parts, original sporopollenin
