本文对唐山和卢龙地区寒武-奥陶系界线地层中的牙形刺再次进行研究,厘定了过去报道的一些重要属种,并对最具地层意义的Cordylodus的几个种的演化进行了分析。指出了该属的两个进化系列,第一支进化系列是Eoconodontusnotchpeakensis-Cordylodusprimitivus-C.proavus-C.caboti-C.intermedius-C.angulatus;而另一支则是Eoconodontusnotchpeakensis-C.caboti-C.prolindstromi-C.lindstromi-C.prion。本文对寒武-奥陶系界线的几个划分方案也进行了简单的讨论  相似文献
