长城群高于庄组主要分布于我国华北地区 ,地质年龄约在 14～ 16亿年。主要描述了华北太行山北段灵邱县境内高于庄组白云岩中的层状和扁豆状透镜体燧石及穹隆式叠层石的黑色燧石中的颤藻、念珠藻和色球藻植物的 8个新种和 3个未定种 ,其中还有两个新修订属。这些新的种群再加上前人在高于庄组地层中已报道的汇成了近 10 0个种生物组合 ,进一步证明高于庄组是地球上中元代微化石类群最丰富的产地之一。以下是该组新发现和新修订的分类类群 :颤藻科 (Oscillatoriaceae) :Eophormidiumorculiformissp .nov.,E .sp .,Siphonophycuscaudataceoussp .nov.,Palaeolyngbyacomplanatasp .nov.,P .capitatasp .nov.,P .sp .,Oscillatoriopsissp .;念珠藻科 (Nosto caceae) :Veteronostocalevaginatasp .nov.;色球藻科 (Chroococcaceae) :Maculosphaeragigantasp .nov .,Gloeotheceopsisgrandissp .nov .;分类位置未定的类群 :Myxococcoideslimpidasp .nov
The Great Wall Group Gaoyuzhuang Formation is mainly distributed in North China, with an age of about 1.4 ~ 1.6 billion years. Mainly describes the black flint in the flint, nostalgia and chlorella plants of the stratiform and lenticular lens chert in the Gaoyuzhuang dolomite of Lingyu County in northern part of the North China Taihang Mountains A new species and three undetermined species, of which there are two newly revised genus. These new populations, together with the reported assemblages of nearly 100 species in previous formations in the Gaoyuzhuang Formation, further prove that the Gaoyuzhuang Formation is the richest origin of the Mesozoic microfossil groups on Earth one. The following are the newly discovered and newly revised taxonomic groups in this group: Oscillatoriaceae: Eophormidium corcilliformissp. Nov., E. sp., Siphonophycus caudataceoussp. Nov., Palaeolyngbyacomplanatasp. Nov., P.capitatasp. Nov., P.sp ., Oscillatoriopsissp .; Nostoc caceae: Veteronostocalevaginatasp. Nov .; Chroococcaceae: Maculosphaeragigantasp. Nov., Gloeotheceopsis grandissp. Nov .; taxonomic group: Myxococcoideslimpidasp .nov
