摘要
在用醋酸浸泡处理采自贵州瓮安新元古代陡山沱组磷酸质岩石样品时 ,获得大量微体动物骨骼化石。文中重点报道部分管柱状微体化石 ,即 :Sinoquadraticusporatusgen .etsp .nov .和Sinoquadraticuswenganensisgen .etsp .nov .。并对Sinocyclocylicus的部分特征进行补充。
In 1992 Xue et al. reported some skeletal fossils, including one genus and two species, from the Neoprotorozoic Doushantuo Formation at Weng'an, Guizhou, and assigned them to Echinodermata. In this paper, new materials of phosphatized cylindrical and tabulate microfossils, including a new genus and two new species, are described from the same layer and locality. It provides us much more evidence not only to display the Neoproterozoic biodiversity, but also to explore the origin and the early evolution of biomineralization.
