The Naobaogou Formation is a geological formation in the Daqing Mountains of China. It is likely of Lopingian (Late Permian) age. It consists of three rhythms of sediment, labelled members I-III primarily of purple siltstone, but each with a thick basal conglomerate bed. It is notable for its fossil content, producing one of the most diverse Late Permian vertebrate faunas outside Russia and South Africa.[1]
5 additional morphotypes in addition to Daqingshanodon and Turfanodon, 2 of which are closely related to the former taxon and 3 or 4 related to Jimusaria.[4][5]
