| 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| Basis of coordinate: | unpublished field data | ||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: | -112 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 unconformably overlain by the Castilletes Formation. This area and nearby collections have been previously mapped as Castilletes Formaton (late Pliocene-early Pleistocene). AGE: Burdigalian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From 112 m below Jimol/Castilletes contact. | |||||
