Abstract: Chancelloriids is a kind of typical Cambrian fauna with an enigmatic biological affinity. Isolated sclerites of chancelloriids
are widespread in Cambrian sedimentary rocks, but chancelloriid sclerites have been seldom reported from the Cambrian of North
China. Herein we described some isolated sclerites of chancelloriids from Cambrian rocks of this area. Specimens were collected from
three localities, i.e., Weifang, Tangshan and Dalian. The isolated sclerites were identified as Chancelloria. According to trilobite
biostratigraphy of the co-occurring trilobites, the age of Chancelloria sclerites from Dalian is considered as Stage 4, Cambrian Series 2;
the age of sclerites of Chancelloria sclerites from Weifang is considered as Wuliuan-Drumian, Cambrian Miaolingian; the age of
Chancelloria sclerites from Tangshan is considered as Jiangshanian, Furongian, and these sclerites are the latest occurrence in China
and one of the latest occurrences in the world. The Chancelloria sclerites from Cambrian Stage2-Furongian, North China, show that
these sclerites tend to be more regular, the basal surfaces tend to be flatter and the integration and organization of sclerites got
improved. These support the conclusions of previous studies.
