Jebel Salakh, Member A [Natih Fm] (Cretaceous of Oman)

Where: Oman (22.3° N, 57.3° E: paleocoordinates 1.6° S, 46.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Natih Formation (Wasia Group), Early/Lower Turonian (93.5 - 89.3 Ma)

• STRATIGRAPHIC RELATIONS: From informal member A of the Natih Fm, which overlies the Nahr Umr Fm (Early to mid-Albian), and is overlain unconformably by the Fiqa Fm (Santonian). AGE: Early Turonian, on the basis of ammonite and microfossil biostratigraphy, and stratigraphic position. STRATIGRAPHIC POSITION: From near top of formation.

• bed-level stratigraphic resolution

Environment/lithology: lithified, shelly/skeletal limestone

• ENVIRONMENT: Shallow marine carbonate setting.
• SPECIFIC LITHOLOGY: Limestone, with microbioclasts. LITHIFICATION: Lithified on the basis of figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression
