Where: Somalia (11.2° N, 49.0° E)
• Paleocoordinates: 7.5° N, 48.5° E (Wright 2013)
• 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
Size class: macrofossils
Collection methods: COLLECTOR: G. Facca, G. Merla, 1938-1939. REPOSITORY: Museo dell' Istituto Geologico dell' Universitá di Firenze.
