| 摘 要： | 在山东莱芜-新泰地区盘车沟剖面固山组底界上下首次发现了副蝴蝶虫(Parablackwelderia).研究表明Parablackwelderia是独立的属,而非Blackwelderia的晚出异名.长期以来,作为我国华北寒武纪崮山组和崮山阶(期)的标准地区,山东的崮山组被认为与崮山阶完全相当,这个认识在莱芜-新泰地区需...

| Abstract: | Parablackwelderia Kobayashi,1942 is recorded for the first time from the lower part of the Gushan Formation at the Jiulongshan and Panchegou Sections,western Shandong.We concluded that Parablackwelderia is a valid genus,not a junior Synonym of Blackwelderia.For a long time,as the type area of the Cambrian System of North China,the Gushan Formation of Shandong has been equated to the Gushanian Stage,but this is incorrect at least in the Laiwu-Xintai area.New fossils indicate that the lower part of the Gushan... |
