Time
| Period: | Neogene | Epoch: | Miocene |
| Stage: | Langhian | 10 m.y. bin: | Cenozoic 5 |
| Key time interval: | Langhian | ||
| Age range of interval: | 15.98000 - 13.82000 m.y. ago |
Stratigraphy
| Formation: | Castilletes | Member: | upper Castilletes | ||
| Local section: | Topio | Local bed: | 90 m | ||
| Local order: | bottom to top | ||||
| Regional section: | Cocinetas | Regional bed: | 423 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: 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 upper part of the Castilletes Fm; from 423 m above Jimol/Castilletes contact. | |||||
