The Miaolingian is the third Series of the Cambrian Period, and was formally named in 2018.[4] It lasted from about 509 to 497 million years ago and is divided in ascending order into 3 stages: the Wuliuan, Drumian, and Guzhangian. The Miaolingian is preceded by the unnamed Cambrian Series 2 and succeeded by the Furongian series.[5]

It is named after the Miaoling Mountains in southeastern Guizhou Province, China.[2]
