摘要: 1986年笔者等在大连棋盘磨等地的金县群兴民村组中部王家坦页岩段页岩层中发现后生动物类水母化石;在金州北山等地的葛屯组页岩层中发现类水母化石、蠕虫化石、可疑小壳类化石和后生植物宏观藻类化石等,丰富了我国震旦系的古生物学内容,对辽南震旦系—寒武系界线的厘定提供了古生物学依据。

Abstract: In 1986, the author discovered fossils of metazoan medusinites in a shale bed of the Wangjiatan Shale Member of the middle Xingmincun Formation of the Jinxian Group in Qipanmu, Dalian, as well as fossils of medusinites, worms, dubious small-shelled metazoans and macroscopic algae in a shale bed of the Getun Formation in the Beishan Mountain, Jinzhou. This enriches the content of the Sinian paleontology of China and furnishes paleontological evidence for the definition of the Sinian-Cambrian boundary in southern Liaoning.
