- •
The conodont stratigraphy of a Guadalupian–Lopingian pelagic chert was examined.
- •
A record of organic carbon isotopes from the same interval is presented.
- •
未13C values in the Roadian–Wordian interval were relatively high.
- •
未13C values gradually decreased during the Capitanian–Wuchiapingian interval.
- •
The 未13C decrease can be correlated with excursions in other sections.
