A systematic revision of the oryctocephalid trilobites provides additional data for the definition of a revised zonation of the Cambrian Series 2‐Series 3 boundary at Balang in South China. The zonation offers a new understanding of the biostratigraphical correlation of this debated limit. The biostratigraphical revision was carried out in the Wuliu‐Zengjiayan Section and provides the following trilobite...
Monkaspis daulis (Walcott [Walcott, C.D., 1905]) is the first enrolled trilobite to be documented from the Kushan Formation (Guzhangian, Cambrian Series 3) of Northern China. It has a wide pygidium that allowed a sphaeroidal enrolment type to be achieved, covering the cephalon and anterior trunk segments. Monkaspis daulis is micropygous, but the pygidium is proportionally larger than that of many...
The use of carbon isotope excursion in Cambrian stratigraphical correlation is a standard practice at both the intercontinental and intracontinental scales. The Steptoean positive carbon isotope excursion (SPICE) is one of the prime examples in this regard in correlating the base of the Paibian Stage and Furongian Series. A lack of definite SPICE evidence in the North China craton has been a challenge...
