Paibian
The Paibian is lowest stage of Furongian series of the Cambrian. It follows the Guzhangian (3rd 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 million years ago. The top, or the base of the Jiangshanian is defined as the first appearance of the ''Agnostotes orientalis'' around million years ago. The name is derived from Paibi, a village in Hunan, China. The GSSP is defined in the "Paibi section" (Wuling Mountains, Huayuan County), an outcrop of the Huaqiao Formation. The base is the first occurrence of ''Glyptagnostus reticulatus'' which is 396 m above the base of the Huaqiao Formation at the type locality ().〔(【引用サイトリンク】url=https://engineering.purdue.edu/Stratigraphy/gssp/paibian.htm )〕 == References ==
