New data on the Cambrian–Ordovician (Tremadocian) conodont biostratigraphy of Guizhou Province, Southwest China

This report documents conodont biostratigraphic successions from the Sandu and Honghuayuan sections located in the southeastern and northern parts of the Guizhou Province. The Sandu section, palaeogeographically located close to the inner margin of the Jiangnan Slope, contains two proto-and paracono...

Summary:This report documents conodont biostratigraphic successions from the Sandu and Honghuayuan sections located in the southeastern and northern parts of the Guizhou Province. The Sandu section, palaeogeographically located close to the inner margin of the Jiangnan Slope, contains two proto-and paraconodont assemblages of the Miaolingian to early Furongian age recovered from the Sandu Formation and latest Furongian to early Tremadocian Cordylodus lindstromi and Cordylodus angulatus zones recovered from the overlying Guotang Formation. The Honghuayuan section, located within the Sichuan Basin in the central part of the Yangtze Platform, contains middle Tremadocian conodonts of the Rossodus manitouensis and Paltodus deltifer zones. This conodont zonation permits biostratigraphic correlation with the Miaolingian to Tremadocian successions in other parts of South China and biozonal successions across the world.
