west of Candelária, Sesmaria do Pinhal 2 (Triassic of Brazil)

Also known as Guaibasaurus type

Where: Rio Grande do Sul, Brazil (29.7° S, 52.9° W: paleocoordinates 37.0° S, 15.1° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Ictidosauria other zone, Caturrita Formation (Rosario 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)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils
