Also known as Prestosuchus chiniquensis site

Where: Rio Grande do Sul, Brazil (21.6° S, 53.4° W: paleocoordinates 38.3° S, 16.3° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Carnian (237.0 - 228.0 Ma)

• This outcrop is situated in the Faxinal do Soturno structural block of sedimentary rocks (Da-Rosa and Faccini 2005) and belongs to the Pinheiros-Chiniquá Sequence of Horn et al. (2014), characterized by the prevalence of reddish mudstones with subaerial exposure and carbonate concretions (Rubert and Schultz 2004). The faunal content of the outcrop suggests its inclusion at the Dinodontosaurus Assemblage Zone (França et al. 2013; Pavanatto et al. 2016), biostratigraphically correlated with the Los Chañares Formation in Argentina, which is early Carnian in age (Marsicano et al. 2016). The ‘Posto de Gasolina’ also had yielded other specimens ascribed to Loricata, including several skeletons of Decuriasuchus quartacolonia (França et al. 2011), additional material referred to Prestosuchus chiniquensis (UFRGSPV-0629-T; Mastrantônio 2010), and isolated elements without a less inclusive taxonomic description.
