摘要：

通过对石门杨家坪地区早寒武世三叶虫动物群研究,建立了(1)Hunanocephalus 带、(2)Arthrico-cephalus-Changaspis 带、(3)Megapalaeolenus-Palaeolenus 带、(4)Probowmania-Yuehsienszeella 组合。生物古地理特征分析表明,自沧浪铺晚期开始,杨家坪地区生物区系应属扬子区,从而更新了研究区早寒武世生物区系属过渡区的传统观点,并建立了 Hunanocephalus、Arthricocephalus、Redlichia takooensis、R.hupehensis、Palaeolenus、Redlichia-Yuehsienszeella 等群落。

Abstract:

Studied the Early Cambrian trilobite faunas collected from Yangjiapingin of Shimen County,Hunan Province,four fossil zones(assemblages)have been established such as Hunanocephalus zone,Arthricocephalus zone,Megapalaeolenus-Palaeolenus zone and Probowmania-Yuehsienszeella assemblage.According to the analysis of the Early Cambrian paleobiogeography of the research area,Yangjiaping biogeographic area should belong to Yangzi biotic province ever since late Canglangpu age,and six communities such as Hunanocephalus community,Arthricocephalus community,Redlichia takooensis community,R.hupehensis community,Palaeolenus community,Redlichia-Yuehsienszeella community have been established.This thus renewed the tranditional view of the area being a transi-tional biogeographic area in Early Cambrian.
