【Abstract】 From September to October in 2000, a fieldwork was carried out for more than one month at several sections, such as Ercaicun and Mafangcun sections in Haikou town, Kunming city, Maotianshan, Ma’anshan and Xiaolantian sections in Chengjiang County, Yunnan Province. During the fieldwork, some new specimens were collected. Among them, three specimens are found separately to be rare arthropods Pisinnocaris sp., Tanglangia longicaudata Luo et Hu, 1999 and Pygmaclypeatus daziensis Zhang, Han et Shu, 2000 reported recently from the Chengjiang Fauna. All materials belong to the Eoredlichia-Wutingaspis Zone of Yu’anshan Member, Heilingpu Formation, Qiongzhusi Stage, Lower Cambrian(Luo et al., 1994).
