Cabecera del río Mañero, km 126, Ruta 26 (Triassic of Argentina)

Also known as Neoaetosauroides holotype; head of the Manero river

Where: La Rioja, Argentina (30.0° S, 67.9° W: paleocoordinates 39.1° S, 31.4° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Los Colorados Formation (Agua de la Peña Group), Norian (221.5 - 205.6 Ma)

• highest levels of formation; formation is considered to be latest Triassic in age

• bed-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; red sandstone

• "The sequence was interpreted as deposited by moderately sinuous fluvial systems, which laterally interfinger with and grade into horizontally bedded flood-plain deposits. To the top of the sequence, thin-bedded sandstones and siltstones dominate and were deposited in ponds and as crevasse splays in overbank settings" (Arcucci et al. 2004)
