Time
| Period: | Neogene | Epoch: | Miocene |
| Stage: | Burdigalian | 10 m.y. bin: | Cenozoic 5 |
| Key time interval: | Santacrucian | ||
| Age range of interval: | 17.40000 - 16.20000 m.y. ago |
Stratigraphy
| Formation: | Santa Cruz | Member: | Estancia La Costa | ||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: The age of this level is between 17.3 and 17.6 Ma, based on the age of two radiometrically dated tuffs that bracket it: the CO tuff of Perkins et al. (2012) and the CV-13 tuff of Trayler et al. (2020). The former as refined by high-precision U–Pb age modeling is 17.31 Ma and the latter is 17.62 Ma (Trayler et al., 2020).
