| Stratigraphy comments: The age of these deposits is not well established (Anaya et al., 1989). Shockey et al. (2007) proposed a Pliocene age for these sediments, whereas Cerdeño et al. (2012) considered them late Miocene. However, the presence of Megatherium (M.) altiplanicum and the low diversity of the mesotheriid taxa (M. Fernández Monescillo, pers. comm.) suggest that an early Pliocene age (i.e. Montehermosan–Chapadmalalan SALMAs) would be more consistent for the Casira fauna | |||||
