Abstract：Representative specific taphonomic fossil-lagerstatten， i.e. the Chengjiang biota， Kaili biota， Niutitang biota and Qingjiang biota etc.， which were successively found from the Cambrian strata of the Yangtze Massif or Yangtze Basin covering the present Yunnan， Guizhou， Hunan and Hubei， are briefly introduced and compared with the Canadian Burges shale biota in this paper. Meanwhile， the horizon， age and assemblage characteristics of the Qingjiang biota found recently in Hubei Province are further discussed and analyzed in comparison with the above-mentioned biotas in the ecology and burial environment. It is suggested that emerge of large-scale soft-bodied bilaterians and the skeletalization of multiple metazoan are the most important feature of the Cambrian explosion. The discovery and study of these biotas above indicate the objective existence of the Cambrian explosion， while also show that biological evolution is not always along the Darwin's progressive evolutionary trajectory from low to high level by means of survival competition and natural selection. As long as the environment permits， a large number of phylum-order organisms is able to appear in a relatively short period of time， using a pattern of explosive and diverse radiation evolution， and this kind of evolution model is of epoch-making significance in the course of biological evolution.The pre-Cambrian Jinning orogenic event affecting about 1 to 0.8 billion years ago in the south of China triggered by the rifting and convergence of Rodinia supercontinent， and the dramatic changes in the levels of organic matter and oxygen and carbon dioxide in the atmosphere and water caused by warming after the snowball event， especially the increase in oxygen production in the air and seawater， provides the necessary prerequisite for the explosion of Cambrian animals in the Yangzi Basin. It also creates excellent living conditions for animal reproduction and skeletalization. However， only those biotas that lived in relatively deep water， oxygenated on the surface water column while deoxygenated at the bottom and situated paleogeographically in the shelf， marginal slope， depression or deeper water basins， such as the Yanjiahe biota， Chengjiang biota， Kaili biota， Niutitang biota and Qingjiang biotas， would be preserved in the oxygen-deprived sea bottom and form black and dark grey shale or mudstone specific taphocoenosis or fossil lagerstatten.
