Also known as SRA
Where: Ica, Peru (14.8° S, 75.4° W)
• Paleocoordinates: 14.0° S, 70.8° W (Wright 2013)
• coordinate stated in text
• local area-level geographic resolution
When: Chilcatay Formation, Burdigalian (20.4 - 16.0 Ma)
• 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).
