Where: Rio Grande do Sul, Brazil (29.5° S, 53.4° W: paleocoordinates 37.0° S, 15.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Ictidosauria other zone, Caturrita Formation (Rosário do Sul Group), Norian (228.0 - 208.5 Ma)

• upper layers of the Santa Maria 2 Sequence of the Santa Maria Supersequence, corresponding lithostratigraphically to the Caturrita Formation. Ictidosauria or Mammaliamorpha Assemblage Zone (= Jachaleria Interval)

•

•Caturrita was originally considered Carnian-Norian in age; however, recent recalibration of the Triassic timescale suggests a Norian age (e.g. Langer et al. 2010; Brusatte et al. 2010. Earth-Science Reviews 101:68-100)
