主要报道了采自云南省昆明市海口马房村鞍山早寒武世筇竹寺组玉案山段澄江生物群中的叶状红藻-似红叶藻(新属、新种)(Paradelesseria sanguinea Xu,gen.et sp.Nov.).通过比较形态学研究,探讨了该宏观化石藻类的分类归属与亲缘关系,进一步丰富了澄江生物群生物物种多样性的认识,并为研究早寒武世生物演化及其古环境提供了新的化石证据.同时,通过对现生红藻的比较研究,进一步证明了澄江生物群在云南海口地区发生于一个水深在30 m以上的亚潮带和下潮间带的海水环境.

This paper deals with the new leaf-like rhodophycean fossils in the Early Cambrian from Chengjiang Biota at Mafang Village of Haikou, Kunming, Yunnan, Southeast China. The new taxa Paradelesseria sanguinea gen. et sp. nov. is found to have a close relationship with the living Delesseria according to detailed morphological study between the fossil and modern Delesseria. These new findings show that the Chengjiang Biota is high in species diversity of fossil algae and might offer new evidence for a better understanding of the Cambrian explosive biological evolution and its paleoenvironment. The Biota in Haikou district of Kunming was living in subtidal and lower intertidal marine environment, up to 30 m below surface of the water based on the comparative study of extant red algae.
