摘　　要：本文描述了贵州剑河八郎“清虚洞组”产出的碎片玛拉利亚藻Morania fragmenta Walcott,1919、穗状玛波利亚藻Marpolia spissa Walcott,1919、线状陡山沱藻Doushantuophyton lineare Steiner,1994,emend.Ye et al.,2019和帚状陡山沱藻Doushantuophyton cometa Yuan et al.,1999。整个“清虚洞组”宏观藻类组合已达5属6种,该组合特征及其主要分子的形态特征与上下地层中的宏观藻类组合相比均有一定的差异,是研究宏观藻类的系统分类及早期植物演化、“清虚洞组”沉积环境和生态环境的重要化石材料。This paper reports 3 macroalgal genera and 4 species from the“Tsinghsutung Formation”(Duyunian Stage,Qiandongian Series,Cambrian) of Jianhe County,Guizhou Province,China.The specimens are assigned to Doushantuophyton lineare Steiner,1994,emend.Ye et al.,2019,Doushantuophyton cometa Yuan et al.,1999,Morania fragmenta,Walcott,1919 and Marpolia spissa Walcott,1919.The latter two genara are the most common kinds of macroalgae in the Kaili Biota,so the macroalgal biota of the“Tsinghsutung Formation”appears to be similar to that of the Kaili Biota.Therefore,the the macroalgal biota of the“Tsinghsutung Formation”reaches 5 macroalgal genera and6 species.The discovery and taxonomic study of these maroalgae provides new information on the evolutionary history of macroalgae in Cambrian,and on the relationship between the evolution of algae and the environment.
