摘要

ace="Times New Roman">Dinosaur and egg fossils were found in 12 Upper Cretaceous basins of ace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />ace w:st="on">aceName w:st="on">ZhejiangaceName> aceType w:st="on">ProvinceaceType>ace>, and in some basins both dinosaur and egg fossils were observed. Except for ace w:st="on">aceName w:st="on">JinquaceName> aceType w:st="on">BasinaceType>ace> 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. According to characteristics of biostratigraphy, isotopic data (101ace="Times New Roman">90 Ma) 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 aceName w:st="on">ZhejiangaceName> aceType w:st="on">ProvinceaceType> are of great significance in the subdivision of the Upper Cretaceous strata in ace w:st="on">aceName w:st="on">ZhejiangaceName> aceType w:st="on">ProvinceaceType>ace>. ace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
