Three palaeoscolecidan new species, namely Yunnanoscolex magnus gen. et sp. nov., Wudingscolex sapushanensis gen. et sp. nov., Paramaotianshania zijunia gen. et sp. nov., and a new corynetiid species, Corynetis fortis sp. nov. are described. The lifestyles of these animals and their ecological significance are discussed. The occurrence of abundant and diverse priapulids from both the Chengjiang and Guanshan fossil Lagerstatten in East Yunnan indicates a possible radiation centre of this animal group on the soft-substratum shelf of the western part of the Yangtze Platform.
