Where: Egypt (30.1° N, 31.1° E)
• Paleocoordinates: 14.0° N, 37.2° E (Wright 2013)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Rotalia- Trochammina foram zone, Abu Roash Formation, Late/Upper Cenomanian (100.5 - 93.9 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
Size classes: macrofossils, mesofossils, microfossils
Collection methods: bulk,
