Stratigraphy
| Formation: | Castilletes | Member: | upper Castilletes | ||
| Local section: | Punta Gorda sud | Local bed: | 0 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: Langhian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From approximately 314 m above the Jimol/Castilletes contact. | |||||
