Also known as Koltayevo III

Where: Bashkortostan, Russian Federation (52.5° N, 53.5° E: paleocoordinates 33.6° N, 41.5° 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 (to which this locality would belong) 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

Environment/lithology: deltaic; gray, yellow sandstone

Size class: macrofossils

Reposited in the PIN
