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: | Castilletes | Member: | lower Castilletes | ||
| Local section: | Kaitamana | Local bed: | 68 m | ||
| Local order: | bottom to top | ||||
| Regional section: | Cocinetas | Regional bed: | 28 m | ||
| Regional order: | bottom to top | ||||

| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware 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: Probably from lower Castilletes Formation, in lower (Patajau - informal) member; from 28 m above the Jimol/Castilletes contact. | |||||
