Geography
Country: | Peru | State/province: | Ica |
Coordinates: | 14.6° South, 75.6° West (view map) | ||
Paleocoordinates: | 15.5° South, 71.5° West | ||
Basis of coordinate: | stated in text |
Time
Period: | Neogene | Epoch: | Miocene |
Stage: | Burdigalian | 10 m.y. bin: | Cenozoic 5 |
Key time interval: | Burdigalian | ||
Age range of interval: | 20.44000 - 15.97000 m.y. ago |
Stratigraphy

Stratigraphy comments: Acosta Hospitaleche et al 2005 identify this locality as early Middle Miocene. Varas-Malca et al 2011 state it is late Oligocene to early middle Miocene.
The age of the Ct1c facies association is constricted between 19.25 ± 0.08 Ma and 19.00 ± 0.28 Ma (early Burdigalian) on the basis of two volcanic ash layer samples dated by 40Ar/39Ar [89]. |
