Permian ammonoids with perrinitids are reported from Kalpin and Qiemo areas in Xinjiang, northwest China. Nine species, representing nine genera: Parapronorites, Propinacoceras, Medlicottia, Eothinites, Agathiceras, Prostacheoceras, Metaperrinites, Perrinites, and Tauroceras are described from the Yesanggang Formation of the Qiemo area. Strong uniformity in Permian ammonoid biostratigraphy and provincialism between Xinjiang and Pamir is suggested.
