Abstract: The red coarse-grainded clastic rock series in the Wulichuan basin of central-east Qinling orogenic belt is a kind of molasse formation. According to finding of a few dinosar eggs and spores, together with isotopic ages and analyzing of evolution history of the basin, it is concluded that the red strata belong to middle-early Cretaceous deposition and suggest that the \\\"Majuacun Formation\\\", \\\"Gaogou Formation\\\", \\\"Sanwan Formation\\\", \\\"Sangping Formation\\\" and \\\"Huangsha Formation\\\" should be canceled and the \\\"Zhuyangguan Formation\\\" can be used instead.
-- mentioned taxa include Nanyangosaurus Zhugeii and ootaxa Ovaloolithus sp., O. sangpingensis, Paraspheroolithus sp. [also spelled Pasaspheroolithus], P. shizuwanensis, Youngoolithus sp., Y. xiaguanensis, Faveoloolithus sp., and Dendroolithus sp.
