Time
Period:Triassic Epoch:Middle Triassic

Stratigraphy
Formation:Donguz
Stratigraphic resolution:group of beds
Stratigraphy comments: 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. It is not clear whether this locality belongs to the lower or upper part of the Donguz Svita/Gorizont
