In this paper, we describe new materials of pterygotid eurypterid Erettopterus sp. excavated from the lower Silurian (Llandovery) Majiaochong Formation of Guizhou Province, China. Those materials represent one of the earliest records of the genus Erettopterus, thereby indicating their long-lived history within the South Chinese region, and might have accomplished global distribution earlier than the previous estimated.
