Bagé-Aceguá Highway, Provelosaurus type (Permian to of Brazil)

Where: Rio Grande do Sul, Brazil (31.8° S, 54.2° W: paleocoordinates 48.2° S, 30.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Rio do Rasto Formation (Passa Dois Group), Roadian to Roadian (272.3 - 259.9 Ma)

• The beds from which vertebrates come are correlated with the Tapinocephalus Assemblage Zone (Karroo) and the Isheevo Complex (Russia), which are Capitanian or Wordian to Capitanian in age (Cisneros et al. 2005, fig. 6; Tsuji & Müller, 2008, Can. J. Earth Sci. 45, fig. 2). For discussion see Cisneros et al. (2005, p. 21).

•Subsequently suggested to be of Roadian to Wordian age on the basis of the temnospondyls from this local area by Pacheco et al. (2017)

• bed-level stratigraphic resolution
