通过对中国南方二叠系-三叠系界线附近十余条深水相剖面的海相无脊椎动物的研究,发现该动物群有如下特点:1)以浮游动物放射虫、游泳动物头足类、个体小且壳体薄的腕足类和双壳类以及少量小个体有孔虫为特征,总体上,动物群的属级(大部分门类的种级)分异度低。2)放射虫非常丰富,除了富产球形放射虫Entactinaria和Spumullaria以外,深水分子Albaillellaria或者Latentifistularia也十分丰富。3)在腕足类分类学组成方面,以Chonetidina和chonetid-like Productidina为主,占腕足类种的数量的50%,其次为Spiriferida,non-chonetidines Productida,Athyridida,Orthida,Orthotetida,Rhyn-
Based on the studies of more than ten marine invertebrates near the Permian-Triassic boundary in southern China, it is found that this fauna has the following characteristics: 1) Based on zooplankton larvae, cephalopods of swimming animals, Individual small and thin shells of brachiopods and bivalves and a few small individual foraminifera characterized, in general, animal genus (most of the species of the species) low degree of differentiation. 2) Very rich in radiolarians. In addition to the genera Entactinaria and Spumullaria, the deep-water molecules Albaillellaria or Latentifistularia are also abundant. 3) In terms of the taxonomic composition of Brachiopods, Chonetidina and chonetid-like Productidina accounted for 50% of the total number of Brachiopods species, followed by Spiriferida, Non-chonetidines Productida, Athyridida, Orthida, Orthotetida and Rhyn-
