Loc. 95, bed H - Dubar Fm (Miocene of Somalia)

Where: Somalia (11.2° N, 49.0° E: paleocoordinates 10.8° N, 47.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Dubar Formation (Guban Group), Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Dubar Fm [enterers usage] of the Guban Series [group?], and presumably regionally overlies Early Miocene strata (equivalent to the Naag Fm) and is overlain by the Late Miocene conglomerate. AGE: Middle Miocene, equivalent to Helvacean and lowermost Mekran according to author on the basis of larger formaniferal and molluscan biostratigraphy. Ostrea virleti is indicator for this zone. STRATIGRAPHIC POSITION: From bed H near middle of section.

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, white reef rocks

• ENVIRONMENT: Shallow subtidal carbonate environment.
• SPECIFIC LITHOLOGY: Calcare coralligeno. LITHIFICATION: Lithified on the basis of figured specimens from adjacent beds.

Size class: macrofossils

Collection methods: COLLECTOR: G. Facca, G. Merla, 1938-1939. REPOSITORY: Museo dell' Istituto Geologico dell' Universit√° di Firenze.
