Geography
| Country: | Colombia | State/province: | La Guajira |
| Coordinates: | 11.9° North, 71.4° West (view map) | ||
| Paleocoordinates: | 11.2° North, 68.2° West | ||
| Basis of coordinate: | unpublished field data | ||
| Geographic resolution: | small collection |
Time
| Period: | Neogene | Epoch: | Miocene |
| 10 m.y. bin: | Cenozoic 5 | ||
| Key time interval: | Burdigalian - Langhian | ||
| Age range of interval: | 20.44000 - 13.82000 m.y. ago |
Stratigraphy
| Formation: | Castilletes | Member: | lower Castilletes | ||
| Regional section: | Cocinetas | Regional bed: | 49 m | ||
| Regional order: | bottom to top | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware Formation. AGE: Burdigalian-Langhian, on the basis of macrofaunal composition and stratigraphic position; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: Likely in lower part of the Castilletes Fm, but in a faulted part of the sequence; from 49 m above Jimol/Castilletes contact. | |||||
