| 摘 要： | 五峰组以盛产笔石动物群著称,时代为凯迪晚期(相当于英国的阿什极尔期),其中也发现了放射虫.该时期的放射虫在全球并不多见.本文首次描述江苏句容仑山地区五峰组的放射虫动物群,该动物群以不具刺的球形放射虫最为发育,并出现少量Inaniguttidae科的分子,化石保存较差,属种单调,分异度很低,这些特点与大西洋沿岸地区陆表海...

| Abstract: | Ordovician radiolarians have been reported from intervals ranging from the Tremadocian to early Kaitian,but so far not yet from late Katian globally.Herein we report the discovery of radiolarians from the Wufeng Formation of late Katian(Ashgill) age at the Lunshan section,Jurong,Jiangsu Province,South China.The Wufeng Formation is lithologically typified by black shale and cherts,and has been well-known for containing diverse graptolite fauna.The yielded radiolarian fauna,though in a low diversity,is charac... |
