Recently lots of the Early Cambrian fauna were described from the Yunnan Province of China. The faunaoccurs from the Maotiangshan shale that dated betwen 525 and 520 ma, which is about 10-20 million years earlier thancomprises an extremely diverse faunal assembly, and soft body parts of the fauna are well preserved. Such conditionprobably resulted from repeated rapid burial environment that prevented the bodies from destruction by currents,bioturbation, and biolchemical activities..........
