| Paleocoordinates: | 7.2° North, 69.1° East |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | outcrop |
Time
| Period: | Paleogene | Epoch: | Eocene |
| Stage: | Ypresian | 10 m.y. bin: | Cenozoic 2 |

Stratigraphy
| Geological group: | Upper Ranikot | ||||
| Local order: | bottom to top | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Limestone unit (2 ft thick), 107 ft from base of 365 ft thick section, underlying sandstone, and overlying shale. This is the lowermost Upper Ranikot, and conformably overlies the Lower Ranikot Series, and is unconformably overlain by the Laki Series. The upper 300 ft of this section (including the collection) correspond to Vredenburg's Zone 2. Evidence for the lower Eocene age assignment is not presented, but the enterer suspects a microfaunal basis. Unit numbering is of the enterer's iniative and is numbered from bottom to top, each unit representing each of the author's lithological subdivisions. | |||||
