Abstract:
A single individual of sicyophorids is discovered from the early Cambrian Guanshan biota in Yunnan, South China. The new finding represents the third occurrence of sicyophorids following the Chengjiang Lagerst?tte (Cambrian Series II, Stage 3) and the Kaili Lagerst?tte (Cambrian Series III, Stage 4), providing new information of the lifestyle and evolution of this animal group. Limited geographic distribution of sicyophorids indicates that this group is probably an endemic clade of the Cambrian fauna.
