Stratigraphy
| Geological group: | Passa Dois | Formation: | Rio do Rasto | Member: | Morro Pelado |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: "To date, the most valuable biostratigraphic markers recovered from these localities are dinocephalians (a group restricted to the Guadalupian) and the dicynodont Endothiodon (a taxon known from the lower part of the Lopingian). Given the presence of the former in Serra do Cadeado, Fagundes farm and Boqueir~ao farm, we conclude that at least part of the Rio do Rasto Formation can be confidently placed in the Guadalupian. We tentatively correlate Serra do Cadeado strata with those of the Beaufort Group based on the distributions of shared tapinocephalid dinocephalians and Endothiodon, broadly covering the Tapinocephalus AZ through the base of the Cistecephalus AZ (upper Guadalupian to lower Lopingian)."
