引言前寒武纪古生物学与其他古生物学科之间存在差别,从生物学的角度来看,可能是由于它所拥有的生物比较特殊,而且它要借助于地球化学方法来建立生命史模式.但从整体上来看,一般它所论及的问题也是演化古生物学的问题:寻求化石记录中演化模式的证据,并推导可能会产生所观察模式的过程.因此模式与过程就成为前寒武纪与显生宙植物、动物和微
Introduction There are differences between the Precambrian paleontology and other Paleontology disciplines, from a biological point of view, perhaps because of the uniqueness of the organism it possesses and its use of geochemical methods to establish patterns of life history. On the whole, the issues it deals with are generally also problems of evolutionary paleontology: the search for evidence of evolutionary patterns in fossil records and the derivation of the processes that may lead to the observed patterns, so that the patterns and processes become pre-Cambrian and Epiphytic plant, animal and micro
