| Paleocoordinates: | 5.3° North, 44.5° East |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | outcrop |
Time
| Period: | Paleogene | Epoch: | Eocene |
| Stage: | Priabonian | 10 m.y. bin: | Cenozoic 3 |
| Key time interval: | Late Eocene | ||
| Age range of interval: | 37.71 - 33.9 m.y. ago |
Stratigraphy
| Geological group: | Buran | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: Lithostratigraphy is somewhat unclear, but Late Eocene beds appear to correlate with, or be included within, the Buran Group. The Gheldei Formation [enterers usage] of the Hafún Series [group?] of Early Oligocene age presumably regionally overlies the Late Eocene strata. THICKNESS: Difficult to ascertain, but a bed of not great thickness. AGE: Late Eocene, according to author on the basis of larger formaniferal biostratigraphy. STRATIGRAPHIC POSITION: From near base of section. | |||||
