I. Foreword Yunnan’s western region has long been regarded as a typical paleo-trough area. The discovery of the Zhangenganganana fauna in Xiaomao, Gengma, illustrates the platform-type sedimentation of the coastal-shallow sea that belongs to the northern margin of the Gondwanaland during the Permian. This article describes the Early Permian Brachiopods and discusses its significance. This article to Jiang Jiangren, Fan Jiancai, Sun Cheng, Huang Biqiao, Zhu Yanmin, Guo Shaowu and other comrades to help guide the author, thanks.
