28°23′22″N 109°31′33″E / 28.3895°N 109.5257°E / 28.3895; 109.5257 The Paibian is the lowest stage of Furongian series of the Cambrian. It follows the Guzhangian (Miaolingian series of the Cambrian) and is succeeded by the Jiangshanian Stage. The base is defined as the first appearance of the trilobite Glyptagnostus reticulatus around 497 million years ago.^[2] The top, or the base of the Jiangshanian is defined as the first appearance of the trilobite Agnostotes orientalis around 494 million years ago.^[4]
