Unknown locality, between Candelaria and Vera Cruz (Triassic to of Brazil)

Where: Rio Grande do Sul, Brazil (29.7° S, 52.7° W: paleocoordinates 51.3° S, 18.0° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Santa Maria Formation (Rosario do Sul Group), Anisian to Anisian (247.2 - 235.0 Ma)

• From an unknown horizon in the Santa Maria Formation. The synapsid Luangwa is known from Anisian age outcrops in Africa (Ntawere Formation), and Abdala & Sa-Teixeira suggest that this might indicate an Anisian age for at least part of the Santa Maria Formation (usually considered Ladinian-Norian in age), but this remains uncertain

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils

Collection methods: UFRGS: Instituto de GeociÍncias, Universidade Federal do Rio Grande do Sul, Porto Alegre
