e.pose. in natural outcrops ne.r the.Duibian Village. Jiangshan County, Zhe.iang Province. China, the.Duibian B se.tion is propose. as the.boundary stratotype.for the.base.of an unname. stage.te.me. provisionally Cambrian Stage.9. The.propose. position of the.GSSP is 108.12 m above.the.base.of the.Huayansi Formation, at a horizon coinciding with the.first appe.rance.of the.cosmopolitan agnostoid trilobite.Agnostote. orie.talis. This horizon coincide. also with the.first appe.rance.of the.cosmopoli-tan polyme.id trilobite.Irvinge.la angustilimbata. The.se.tion fulfills all the.re.uire.e.ts for a GSSP, and the.horizon can be.constraine. not only by the.primary stratigraphic marke. (A. orie.talis) but also with se.ondary biostratigraphic, che.ostratigraphic, and se.ue.ce.stratigraphic corre.ation tools. The.first appe.rance.of A. orie.talis is one.of the.most re.dily re.ognizable.le.e.s in Cambrian, and can be.corre.ate. with pre.ision to all pale.contine.ts.

The.philosophy of the.Inte.national Subcommission on Cambrian Stratigraphy for e.tablishing a cle.r subdivision of the.Cambrian on a global scale.is unambiguous： stratigraphic te.ms pre.iously in use.lack global applicability and should not be.adopte. as chronostratigraphic/ge.chronologic units in the.de.e.oping global stratigraphic chart of the.Cambrian.
