El Midawara section, Abu Roash, Unit 1 (Cretaceous of Egypt)

Where: Egypt (30.1° N, 31.1° E: paleocoordinates 9.4° N, 25.8° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Rotalia- Trochammina foram zone, Abu Roash Formation, Late/Upper Cenomanian (99.6 - 93.5 Ma)

• time interval uncertain, but :'Based on the determined macrofossil and/or microfossil assemblages and the position of the section in these deposits, the ?late Cenomanian may be assigned to this unit' and 'Most taxa of this fauna are typical Cenomanian index fossils and some of them (particularly Amphidonte (Ceratostreon) flabellata and Ilymatogyra (Afrogyra) africana) have never been reported to extend to the Turonian.'

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; marl and limestone

• marl with a thin intercalated limestone bed

Size classes: macrofossils, mesofossils, microfossils

Collection methods: bulk,
