El-Hassana section, Abu Roash (Cretaceous of Egypt)

Where: Egypt (30.1° N, 31.1° E: paleocoordinates 11.1° N, 25.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Turonian (93.9 - 89.8 Ma)

• Actaeonella Series

Environment/lithology: reef, buildup or bioherm; limestone

• The rudists were accumulated as a 4–5 m thick biostrome associated with the coralline sponge Millestroma nicholsoni Gregory, which is found as isolated mounds or within the rudist biostrome. It is underlain by bioturbated chalky limestone, highly fossiliferous. The rudist biostromes recognized in the Actaeonella Series (Late Turonian) were developed with low to moderate energy on deeper parts of subtidal rudist shoals.
• 4–5 m thick biostrome

Size classes: macrofossils, mesofossils
