| Key time interval: | Burdigalian | ||
| Age range of interval: | 20.44 - 15.98 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). | |||||
