Loc. 39, Bed G - Gianti Fm (Oligocene of Somalia)

Where: Somalia (9.5° N, 50.8° E: paleocoordinates 6.6° N, 45.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Gianti Formation (Hafún Group), Early/Lower Oligocene (33.9 - 28.4 Ma)

• STRATIGRAPHIC RELATIONS: From the Gianti Fm [enterers usage] of the Hafún Series [group?], and presumably regionally overlies the Gheldeis Fm [enterers usage] (Early Oligocene) and is overlain by the Tavo Fm [enterers usage] (Late Oligocene). AGE: Early Oligocene, equivalent to Stampien and middle Nari according to author on the basis of larger formaniferal and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From bed G, near the top of the section.

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, sandy limestone

• ENVIRONMENT: Shallow subtidal carbonate environment.
• SPECIFIC LITHOLOGY: Calcare arenaceo. LITHIFICATION: Poorly lithified on the basis of facies description.

Size class: macrofossils

Preservation: cast, mold/impression
