| Coordinates: | 12.0° North, 71.3° West (view map) | ||
| Paleocoordinates: | 11.2° North, 68.0° West | ||
| Basis of coordinate: | unpublished field data | ||
| Geographic resolution: | small collection |
Time
| Period: | Neogene | Epoch: | Miocene |
| Stage: | Burdigalian | 10 m.y. bin: | Cenozoic 5 |
| Key time interval: | Burdigalian | ||
| Age range of interval: | 20.44000 - 15.98000 m.y. ago |
Stratigraphy
| Formation: | Jimol | Member: | middle Jimol | ||
| Regional section: | Cocinetas | Regional bed: | -105 m | ||
| Regional order: | bottom to top | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Jimol Formation, which conformably overlies the Uipta Formation (early Miocene) and is conformably overlain by the Castilletes Formation. AGE: Burdigalian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From faulted area, but likely in middle part of the Jimol Fm; from approximately 105 m below Jimol/Castilletes contact. | |||||
