The trilobite Bathynotus from Cambrian Series 2 of China and its implications for global correlation

Abstract

The trilobite Bathynotus kueichouensis is widespread, occurring in Siberia, South China, North America and Australia. With a short stratigraphic range and widespread geographic distribution, it is useful for marking the top of Cambrian Series 2 and provides important information for precise correlation of the top of the series.
