The top of the Capitanian is defined as the place in the stratigraphic record where the conodont species Clarkina postbitteri hongshuensis first appears. Jinogondolella posts errata is the last conodont species in the stratigraphic record of the Capitanian . “Maokouan” is a regional stage of Chinese stratigraphy in the earlier Chinese literature that includes the latter part of the Wordian and the entire Capitanian (Bond & Hilton, 2010)

The conodont species appeared in the stratigraphic record of the Capitanian stage were J.granti->J.prexuanhanensis-J.xuanhanensis->J.altudaensis->J.shannoni->J.postserrata

Biostratigraphic Evidence:

By exploring the stratotype at Penglaitan (Guangxi Province) has led to the establishment of a detailed conodont zonation ( Jin et al., 1998, 2001, 2006 ) that has allowed biostratigraphic constraint of the marine microfossil extinction level in sections throughout South China ( Xia et al., 2005; Zhang et al., 2008; Wignall et al., 2009, Bond et al., 2010 ).Unfortunately, the shallow platform carbonates of the Maokou Formation are facies that are not particularly favoured by conodonts, and thus other forms of correlation are required.

Rectostipulina quadrata had occurred around this level further supports this age assignment because this foraminifera appears and is abundant in post-extinction assemblages of the J. granti Zone in South China (Wignall et al., 2009b; Bond et al., 2010a).

Attempts to extract conodonts from Northern Hungarian (Nagyvisnyo ́ Limestone )samples were also unsuccessful. Only a few fragments were found, with the exception of a well-preserved specimen of Jinogondolella granti from the upper part of the section.

Chemostratigraphic:

The Capitanian Stage is marked by heavy δ 13C values, a recently developed carbon isotope stratigraphy ( Wang et al., 2004; Wignall et al., 2009a; Bond et al., 2010 ) has provided an alternative means of correlation. The most notable aspect of the δ 13 C isotope record is a major negative excursion across the extinction-and-volcanic interval (separate to the negative excursion identified at the GLB by Wang et al., 2004 ).
