10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Huayquerian |
Mammal zone: | Huayquerian |
| Age range of interval: | 8 - 5 m.y. ago |
| Formation: | Cerro Azul |
| Stratigraphy comments: The remains from this locality were found in boreholes up to 50 m deep. Other taxa present are not known enough to allow their age to be adjusted. Therefore, the locality is assigned to the Huayquerian sensu lato (late Miocene–early Pliocene). |
| Primary lithology: | not reported |
| Lithology description: Levels with remains in this locality correspond to the Cerro Azul Formation (Linares et al., 1980), characterized by loess-type erosion forms. In general, these are levels of brown silts and sandy silts of primary eolian origin (loess deposits), which have been reworked by aqueous agents (loess-like deposits). Paleosol levels and pedogenic features, as well as carbonate accumulations, including nodules and rhizoconcretions, are common throughout the sequence (Folguera and Zárate, 2009). |
