Abstract: The earliest Cambrian acritarch ‘Asteridium–Heliosphaeridium–Comasphaeridium’ assemblage and the Early Cambrian (‘Chiungchussuan’) acritarch ‘Skiagia ornate–Fimbriaglomerella membranacea’ assemblage in South China can be correlated with assemblages from synchronous strata elsewhere in the world. Recent geochemical study and biomarker evidence further confirm a biostratigraphic change between Cambrian Series 2 and Series 3 and support the recognition of a major geological and biotic event during this time interval.
