Serra do Cadeado, Central Parana Railway (EFCP) (Permian to of Brazil)

Where: Paraná, Brazil (24.0° S, 51.1° W: paleocoordinates 41.3° S, 22.4° W)

• coordinate stated in text

• local area-level geographic resolution

When: Serrinha/Morro Pelado Member (Rio do Rasto Formation), Wordian to Wordian (268.8 - 254.2 Ma)

• "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)." Boos et al. 2015

• member-level stratigraphic resolution

Environment/lithology: fluvial; gray siltstone
