Stratigraphy
Geological group:Hafún Formation:Ghibirti
Stratigraphic resolution:group of beds
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Ghibirti Fm [enterers usage] of the Hafún Series [group?] of Early Miocene, and presumably regionally overlies the Tavo Fm [enterers usage] (Late Oligocene) and is overlain by the Naag Fm [enterers usage] (Early Miocene). AGE: Early Miocene, equivalent to Aquitanian and lower Gaj according to author on the basis of larger formaniferal and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From unknown position within section.
