Madrakah Cliffs - Shuwayr Fm (Oligocene of Oman)

Where: Oman (19.0° N, 57.8° E: paleocoordinates 13.4° N, 52.4° E)

• coordinate stated in text

• local area-level geographic resolution

When: Shuwayr Formation, Chattian (28.1 - 23.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Shuwayr Fm, which is unconformably overlain by the Warak Fm (Chattian). THICKNESS: From section of more than 90 m in thickness. AGE: latest Rupelian-early Chattian. Stated by Harzhauser to most likely be "Late Oligocene". Assigned here to Chattian. STRATIGRAPHIC POSITION: From throughout section, although facies become more marine and fossiliferous upsection.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; poorly lithified, shelly/skeletal marl and poorly lithified, shelly/skeletal limestone

• ENVIRONMENT: Very shallow marine depositional environment. Some evidence of shallow sublittoral setting of a few tens of metres of water depth. Many taxa typical of patch reefs, coral carpets, sea grass meadows, and littoral mangrove flats.
• SPECIFIC LITHOLOGY: Marls and bioclastic limestone. LITHIFICATION: Poorly lithified, based on figured specimens.

Size class: macrofossils
