Stratigraphy
| Formation: | Salicas | ||||
| Stratigraphy comments: Cerdeno and Schmidt 2013: the details on geographic provenance and stratigraphic correlations are described in this paper. Tauber (2005) assigned the faunal remains to the Huayquerian Age (late Miocene) and Brandoni et al. (2012) established correlations with the well-known Neogene beds of the Andalhuala and Chiquimil formations, in Catamarca Province. They considered that the Salicas assemblage can roughly correspond to the range from 6.02 to 6.68 Ma obtained for these levels (Marshall and Patterson, 1981), closer to the recently proposed Huayquerian/Montehermosan boundary for the North- west of Argentina (Reguero and Candela, 2011). |
