Berdyanka II (locality 32), PIN 2865 (Triassic of Russian Federation)

Where: Orenburg, Russian Federation (51.6° N, 55.4° E: paleocoordinates 33.8° N, 43.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Donguz Formation, Anisian (247.2 - 242.0 Ma)

• The Donguz Svita/Gorizont is the "characteristic" tetrapod assemblage for the Perovkan Land Vertebrate Faunachron of Lucas, considered to be of Anisian age (see Lucas 2010). By contrast, Fröbisch (2009) suggested that the lower part of the Donguz Svita/Gorizont is referable to the Nonesian LVF, is of early Anisian age, and can be correlated which subzone B of the Cynognathus AZ of South Africa, while the upper part of the Donguz Svita/Gorizont is referable to the Perovkan LVF, is of late Anisian age, and can be correlated which subzone C of the Cynognathus AZ of South Africa. This locality is from the upper part of the Donguz Svita/Gorizont according to Gower & Sennikov (1997)

• group of beds-level stratigraphic resolution

Environment/lithology: deltaic; fine-grained, yellow sandstone

• "Deltaic deposits"
• "Buff-yellow, fine-grained, cross-bedded sandstone with lenses of conglomerate, clay, and siltstone"

Size class: macrofossils
