•The Cerro Boleadoras Formation contains vertebrate fossils that were respectively assigned to the Santacrucian SALMA (lower Miocene) by Carlini et al. (1993) and Vucetich (1994) and to the Friasian SALMA (upper lower to middle Miocene) by Scillato-Yané et al. (1993) (see Fig. 3). Espinoza et al. (2010) obtained four K/Ar ages between ~16 and 14 Ma for the Zeballos Volcanic Sequence in the top of the Río Zeballos Group (see Fig. 3).
