| Abstract: | We reestablished the Serratognathus bilobatus Biozone in the Taebaek Group of Korea, where Serratognathus bilobatus was first reported by Lee (1970), based on new data from the uppermost Dumugol Formation to the Lower Makgol Formation at the Seokgaejae Section, Taebaeksan Basin. The conodont fauna includes several first-reported species in Korea of Acodus shitaianus, Bergstroemognathus extensus, B. pectiniformis, Paraserratognathus incostatus, Nasusgnathus dolonus, Rhipidognathus yichangensis. The co-occurrence of the Serratognathus bilobatus and comparison of associated species with other continents show similar results with the biogeographic link of eastern Gondwana during the Early Ordovician proposed as the "Australasian Superprovince". The highest similarity with North China reaffirms that Taebaek Group is part of North China paleoplate. The relatively low similarity with western Australia, Tarim, Sibumasu and Kazakhstan, and high similarity with South China indicate that the Taebaeksan Basin was located in closer proximity to South China than other continents during Floian. Serratognathus bilobatus, which occurred from the nodular limestone and lime mudstone in this study, has been recovered in wide range of depositional facies including limestone dominated and siliciclastic-carbonate mixed facies in other continents of eastern Gondwana. This study suggests that the widespread distribution of Serratognathus bilobatus might be related to the depositional environment. [ABSTRACT FROM AUTHOR] |
