Wald Sanga (upper)Montefeltro F. C., Langer M. C., et al (2010)Rosario do Sul - CaturritaLocality is from the upper part of the highstand system tract of the Santa Maria Sequence 2, Santa Maria Supersequence of the Rosario do Sul Group, representing the lower part of the Caturrita Formation of Norian age (see Langer et al. 2007; Montefeltro et al. 2010). Fossils are from a stratigraphically higher level than Hyperodapedon from the same locality. conglomerate228 - 208.5 Ma

(2005)Rosario do Sul - Santa Maria - AlemoaSanta Maria 2 (upper half of Santa Maria Formation), from the so-called "Rhynchosaur Cenozone" or "Hyperodapedon Assemblage Zone". The Hyperodapedon Assemblage Zone has generally considered been late Carnian in age, but could extend into the early Norian.siltstone237 - 208.5 Ma

Wald Sanga, Huene Loc. 1 (5m)Langer M. C. (2005)Rosario do Sul - Santa Maria - AlemoaLocality is from the Santa Maria Sequence 2, Santa Maria Supersequence of the Rosario do Sul Group, corresponding to the Alemoa Member of the Santa Maria Formation, or so-called "Rhynchosaur Cenozone" or "Hyperodapedon Assemblage Zone"(see Langer et al. 2007). The Hyperodapedon Assemblage Zone has generally considered been late Carnian in age, but could extend into the early Norian.siltstone237 - 208.5 Ma

Wald Sanga, Santa Maria (middle)Huene F. v. (1936)Rosario do Sul - Santa Maria - AlemoaSanta Maria 2 (upper half of Santa Maria Formation), from the so-called "Rhynchosaur Cenozone" or "Hyperodapedon Assemblage Zone". The Hyperodapedon Assemblage Zone has generally considered been late Carnian in age, but could extend into the early Norian.
Specimens come from approximately 11 metres above the base of the section at Wald Sanga (see Montefeltro et al. 2010: fig. 1)
