由于Diceratocephalus已在华北的若干地点找到,如莱芜九龙山、淄博黑石寨和泰安大汶口,Dicerato-cephalus三叶虫亚带可以提升为三叶虫带,这样崮山阶便包含了4个三叶虫带(自上而下)Diceratoceph alusarma-tus带、Drepanura premesnili带、Blackwelderia paronai带和Damesella paronai带。
In recent years, the trilobite fossil Diceratocephalus has been discovered in a number of the Cambrian successions in North China, such as Jiulongshan of Laiwu, Heishizhai of Zibo, and Dawenkou of Taian. The Diceratocephalus trilobite Subzone can be promoted to the Diceratocephalus trilobite Zone. Therefore the Gushanian Stage contains 4 trilobite zones: the Diceratocephalus armatus Zone, the Drepanura premesnili Zone, Blackwelderia paronai Zone, and the Damesella paronai Zone.
