【摘要】 1986年我们首次在辽南发现类水母化石和藻类化石,并在大林子组浸泡出小壳动物化石。这一发现对辽南地区寒武系/震旦系界线的确定提供了古生物学依据,同时丰富了该区古生物学内容。类水母化石在兴民村组中段页岩层极其发育,初步鉴定主要种属有:多环辽南水母(新属、新种)Liaonanella Multicyclica Liu et Yang(gen.et sP.nov.),平盘辽南水母(新属、新种)L.Planodisciformis Liu et Yang(gen.etsP.now.),环带金县水母(新属、新种)Jinxianella Zonata Liu et Yang(gen.et sP.nov.),甘井子金县水母J.ganjingziensis Liu et Yang(gen.etsP.nov.),棋盘磨大连水母(新属、新种)Dalianiaqipanmoensis Liu et Yang(gen.et sp.nov.)。宏观藻类化石主要产在葛屯组的页岩层中,化石是:chuaria circularis Walcott,Tawuiadalensis Hofmann。关于这次发现的蠕虫化石、可疑小壳动物化石等正在研究中。更多还原

【Abstract】 Recently,in 1986,medusa-like and macroscopic algae were found from the Getun and Xingmincun Formations and a small shelly fassil were soaked out from the Dalinzi Formation,for the first time in south Liaoning province by the writers.These new materials are the palaeontological evidence for the de- termination of the boundary between Cambrian and Sinian and increase the knowledge of palaeontology in south Liaoning. Medusa-like fossils are very plent- iful in the middle part of the shale member of Xingmincun Formation,the genera and species are given as follows: Liaonanella multicyclica(gen.et sp. nov.),L.planodisciformis(gen.et sp. nov.),Jinxianella zonata(gen.et sp. nov.),and J.ganjingziensis(gen.et sp. nov.),Daliania qipanmoensis(gen.et sp.nov.). Medusa-like(?)and macroscopic algae fossils were discovered from Getun Formation.They are:Chuaria circularis Walcott,and Tawuia dalensis Hofmann. Some verme-like and problematic small shelly fossils collected at that time are preparing.更多还原
