Bed E - Wadi Garap Degá [Gargorre Fm] (Miocene of Somalia)

Also known as Loc. 29

Where: Somalia (10.4° N, 49.3° E: paleocoordinates 10.0° N, 47.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Gargorre Formation (Hafún Group), Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Gargorre Fm [enterers usage] of the Hafún Series [group?], and presumably regionally overlies the Naag Fm [enterers usage] (Early Miocene) and is overlain by the Late Miocene conglomerates. THICKNESS: Difficult to ascertain, but a bed of not great thickness. AGE: Middle Miocene, equivalent to Burdigalian-Helvetian and uppermost Gaj/lower Mekran according to author on the basis of larger formaniferal and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From Bed E, at top of section.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified siliciclastic sediments

• ENVIRONMENT: Shallow shelf siliciclastic environment.
• SPECIFIC LITHOLOGY: Siliciclastic. LITHIFICATION: Lithified on the basis of figured specimens from adjacent beds.

Size class: macrofossils

Preservation: cast, mold/impression

Collected by Facca & Marchesini in 1938-1939

• COLLECTOR: Collected by G. Facca and E. Marchesini, 1938-1939. REPOSITORY: Museo dell' Istituto Geologico dell' Universitá di Firenze.
