The many achievements in the study on. the fossils (in especial megafossils) of late Precambrian - Cambrian in China are outlined. Among them, the organic fossils (including Miaohe Biota and Lan-tian Flora) in the Doushantuo stage of Upper Sinian discovered in recent years demonstrated an important stage for the early diversification of the plant kingdom; the early Cambrian Chengjiang Biota (bearing the soft-bodied fossils and skeletal fossils but with well-preserved soft-parts) is earlier than the famous Burgess shale fauna and very close to the first `explosion'，radiation of the metazoam with hard part(so-called small shelly fossils).The sturdies on such exceptional and valuable fossil communities will lead to reconsidering the evolutionary processes of early life. The prospectsin this field are then brilliant.
