Geography
Country:Peru State/province:Ica
Coordinates: 14.8° South, 75.4° West (view map)
Paleocoordinates:15.7° South, 71.2° West
Basis of coordinate:stated in text
Geographic resolution:local area
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
Formation:Chilcatay
Stratigraphic resolution:bed
Stratigraphy comments: Originally Aquitanian
Muizon calls this formation Caballas, but it is better known as Chilcatay according to Dunbar et al. (1990).

The chronostratigraphic framework for the Chilcatay strata exposed in the study area is well constrained by integration of micropaleontological data and isotope geochronology that indicate deposition between 19 and 18 Ma, during the late early Miocene (i.e., Burdigalian) (Di Celma et al., 2017, 2018).
