The Naobaogou Formation is a geological formation in the Daqing Mountains of China. It is of Lopingian age. It consists of three rhythms of sediment, labelled members I-III primarily of purple siltstone, but each with a thick basal conglomerate. It is notable for its fossil content, producing one of the most diverse Late Permian vertebrate faunas outside Russia and South Africa.

Caodeyao [1] C. liuyufengi Partial skull, mandible, humerus A Eutherocephalian, closely related to Purlovia.
Daqingshanodon[2] D. limbus Skull Dicynodont
Elginia[3] E. wuyongae Partial skull Pareiasaur
Jiufengia[4] J. Jiai Partial skull and postcranial skeleton Akidnognathid Therocephalian
