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: | Patajau norte | Local bed: | 98 m | ||
| Local order: | bottom to top | ||||
| Regional section: | Cocinetas | Regional bed: | 96 m | ||

| 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: From approximately 96 m in regional section. | |||||
