Also known as Rincao dos Weiss; holotype site of Procolophon brasiliensis
Where: Rio Grande do Sul, Brazil (29.6° S, 54.4° W: paleocoordinates 49.1° S, 23.7° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Sanga do Cabral Formation (Rosário do Sul Group), Induan to Induan (252.2 - 247.2 Ma)
• The Sanga do Cabral Fm. is correlated with the "impoverished zone" (Procolophon subzone) of the Lystrosaurus Assemblage Zone of the Main Karoo Basin of South Africa by some authors on the basis of the abundant records of Procolophon, i.e., it is Upper Induan to Lower Olenekian in age (see Dias-da-Silva et al., 2006, Can. J. Earth Sci. and references therein). However, Langer et al. (2007; New Mexico Mus. Nat. Hist. Sci. Bull. 41) pointed out that the prevalence of Procolophon in the Brazilian sequence might represent a taphonomic bias, and that only an undifferentiated Lower Triassic age is currently possible.
