本文系对浙江白垩纪轮藻化石资料系统总结,经研究鉴定计9属22种[其中1新属和7新种(新变种、新组合)]。根据组合特征和地质分布规律,提出了三个轮藻化石组合带。特别是杭嘉湖地区晚白垩世晚期的桐乡组轮藻化石,在生物地层学及阐明找油方向上更具有重要意义。 In this paper, we summarize the data system of charaterotrophic fossil from Zhejiang Province. After research, there are 9 genera and 22 species [including 1 new genus and 7 new species (new variety, new combination)]. According to the characteristics of the combination and the geological distribution, three chara fossil assemblages are proposed. Especially in the late Late Cretaceous of the Hangjiahu region, the Tongxiang Formation Hydrilla verticillata fossils are of great significance in the field of bio-stratigraphy and elucidation of oil-finding directions.
