New Bradoriid Arthropods from the Early Cambrian Balang Formation of Eastern Guizhou, South China
The Early Cambrian Balang Formation is comprised of mudrock and shale, which was deposited in a shelf environment in the eastern part of Guizhou, south China. The Balang Fauna, which consists of seven phyla, occurs in the middle and upper parts of the Balang Formation. Arthropods are important const...
