Eocene–Oligocene ‘Tobas del Sarmiento’, Sarmiento Group or Sarmiento Formation (Feruglio 1949; Andreis et al. 1975; Spalletti & Mazzoni 1977, 1979; Reguero & Escribano 1996). Regarding the age of Sarmiento formation, absolute dates are lacking for Cabeza Blanca, but Deseadan levels have been dated in other localities such as Salla, Bolivia (29.4–25.65 Ma), Moquegua, Peru (26.25 Ma), and Chubut, Argentina, Gran Barranca (29.4–24.2 Ma) and Scarritt Pocket (27.17 Ma) (Dunn et al. 2013 and references therein; Vucetich et al. 2014). |
