Inhamandá 2 (Triassic to of Brazil)

Where: Rio Grande do Sul, Brazil (29.6° S, 54.1° W: paleocoordinates 39.8° S, 16.0° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Hyperodapedon other zone, Alemoa Member (Santa Maria Formation), Carnian to Carnian (237.0 - 208.5 Ma)

• Santa 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.

Environment/lithology: fluvial; red mudstone and fine-grained, red sandstone

• "Mudstones intercalated with fine-grained sandstone layers are the commonest facies of the Santa Maria Formation, and were deposited in the floodplains of a braided fluvial system, under a semi-arid climate" (Langer & Schultz 2000. Palaeontology 43:633)

Size class: macrofossils

Collection methods: quarrying,
