    摘要:

    提要:在浙江省内,有12个白垩纪红层盆地中发现恐龙化石和蛋化石,且多个盆地龙蛋共生。经初步调查, 除金衢盆地衢江群下部中戴组发现恐龙化石外,恐龙化石和蛋化石均产于盆地内的中上部地层:即永康群朝川组、方岩组,衢江群的金华组和衢县组,天台群两头塘组和赤城山组。从相关地层的古生物组合时代和火山岩同位素年龄为101~90 Ma以及地层的古地磁均为正向极性特征分析,浙江绝大部分恐龙蛋的时代应为晚白垩世,而蜂窝蛋类化石时代则很可能是早白垩世晚期或未期。

    Abstract:

    Abstract:Dinosaur and egg fossils were found in 12 Upper Cretaceous basins of Zhejiang Province, and in some basins both dinosaur and egg fossils were observed. Except for Jinqu Basin where dinosaur fossils were found in Zhongdai Formation of Lower Qujiang Group, dinosaurs and egg fossils in all other basins were exclusively produced in the middle and upper strata, i.e., Chaochuang and Fangyan Formations of Yongkang Group, Jinhua and Quxian Formations of Qujiang Group, and Liangtoutang and Chichengshan Formations of Tiantai Group. According to characteristics of biostratigraphy, isotopic data (101-90Ma) and positive polarity paleomagnetism, the authors consider that the age of some fossil eggs in Zhejiang is Late Cretaceous, whereas the age of Faveoloolithidae may be the end of Cretaceous. Researches on dinosaurs and dinosaur egg fossils of Zhejiang Province are of great significance in the subdivision of the Upper Cretaceous strata in Zhejiang Province.
