陆生动物群和植物群以及海洋动物群的分区性是二叠纪一个引人注意的特征。在这一时期,当某一分区模式改变时,某些信息的存在或缺失(如(竹蜓)、有孔虫)、某些信息的稀有和多样性(如牙形石和菊石)以及某些土著的信息(如牙形石和腕足)可以反映其分区性。在不同的古生态小生境中,不同类群的分区性是显而易见的(如定居底栖生物和自游生物)。二叠纪生物的分区性给全球对比带来了困难,即没有单一的类群可较好地用于全球对比。冈瓦纳古陆(占二叠纪全球陆地面积的三分之一)的二叠系可与北方区及欧洲的俄罗斯地区根据多门类生物(如海相腕足及陆生昆虫)较好地进行对比;而与北美及提供了晚二叠世参考剖面的华南的对比则相对较差。二叠纪生物区持续久,地域广(冈瓦纳区、特提斯 The zoning of terrestrial fauna and flora as well as marine fauna is a striking feature of Permian. During this period, the existence and absence of certain information (such as (bamboo-dragonfly), foraminifera), the rarity and diversity of certain information (such as conodont and ammonite) Some indigenous information (such as conodont and brachiopods) can reflect its zoning. In different paleoenvironmental niche, the zoning of different groups is obvious (such as settler beings and self-learning creatures). The division of Permian organisms has caused global comparisons difficulties, ie no single taxon can be better used for global comparisons. The Permian of Gondwanaland (one third of the Permian global land area) can be well established with many types of organisms (such as marine brachiopods and terrestrial insects) in northern regions and Russia in northern Europe Compared with North America and South China where the Late Permian Reference Profile was provided. Permian biological area lasts long, wide area (Gondwanaland, Tethys
