Time
| Period: | Neogene | Epoch: | Miocene |
| 10 m.y. bin: | Cenozoic 6 | ||
| Key time interval: | Late/Upper Miocene | ||
| Age range of interval: | 11.63000 - 5.33300 m.y. ago |
Stratigraphy
| Formation: | Cercado | ||||
| Local section: | El Moro | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: The section starts at sea level with claystone and continues for close to 700 ft with alternating claystone, limestones and uncommon sands. At 675-825 ft the section is capped by a limeston. From unknown formation (Possibly Cercado, Gurabo or Mao) at the time of writing. Faunal similarities suggest that this unit is correlated with strata more recently assigned to the Cercadi Fm. | |||||
