The Ordovician Huangnitang System in Changshan, Zhejiang Province, has a complete stratigraphic sequence accompanied by continuous rock strata and abundant fossils. This section developed through the continuous strata of the Darriwilian Stage of the Middle Ordovician Series. The continuous evolution of graptolites and conodonts allows this section to be a marker for global correlations. The first occurrence of the graptolite zone with Undulograptus austrodentatus fossils led this section to become a Darriwilian GSSP based on the approval of the International Commission on Stratigraphy Ordovician Branch and the International Union of Geological Sciences. It was China’s first ‘Golden Spike’. This section is located in Huangnitang in Erduqiao Village, Changshan County (Zhoutangcun Village),...
