Also known as Locality 36; Dongus river; Perovsky settlement;

Where: Orenburg, Russian Federation (51.4° N, 55.3° E: paleocoordinates 33.6° N, 43.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• Outcrop is ~10 meters high. The author does not explicitly state which layer Lystrosuarus klimovi is from in the english text, but bed 3 is marked in Fig. 24. Detailed lithological descriptions are provided for each bed in the russian text.

•Equivalent to the South African "Cynognathus Zone, corresponding to the Upper Buntsandstein of Germany, or to the Scythian." The Cynognathus Zone has recently been split into three time equivalent assemblages, therefore a Scythian age may not be correct.

•

•Additional note: Tverdokhlebov et al. (2003) assign the locality to the Middle Triassic (Anisian) Donguz Svita. Original stratigraphic data are modified accordingly (TL).

•

•The Donguz Svita is the "characteristic" tetrapod assemblage for the Perovkan Land Vertebrate Faunachron of Lucas, considered to be of Anisian age (see Lucas 2010)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-deltaic; ferruginous, black, gray, green sandstone and lenticular conglomerate

Size class: macrofossils

Preservation: concretion
