Where: Somalia (10.4° N, 51.3° E: paleocoordinates 7.5° N, 46.1° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Gheldeis Formation (Hafún Group), Early/Lower Oligocene (33.9 - 28.4 Ma)
• STRATIGRAPHIC RELATIONS: From the Gheldeis Fm [enterers usage] of the Hafún Series [group?], and presumably regionally overlies Late Eocene strata and is overlain by the Gianti Fm [enterers usage] (Early 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 unknown position within section.
• group of beds-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified limestone
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.
