摘要
The red strata of a suite ofterrigenous clastic rock series of bearing-dinosaur egg and dinosaur skeleton fossils are exposed in the Xiaguan-Gaoqiu Basin of Henan Province.In the late 1970s,the chronologic age of the red strata containing dinosaur eggs was classified as the Cretaceous period by Prof.Zhao Zikui(1979).After this,it has been called Gaogou Formation and Majiacun Formation,Sangping Formation,Xiaguan Formation,but no survey has been conducted on theses stratigraphic sections.The reason is that there are no invertebrate and plant fossils that have been found to determine stratigraphic epoch except the dinosaur skeleton (Nanyangosaurus zhugeii) and dinosaur egg fossils.In recent years,in addition to the discovery of dinosaur skeleton fossil identified and named as Baotianmansaurus,the author chose the systematic stratigraphic sections in 2011 and the invertebrate fossils such as ostracods,bivalves and gastropods,charophyte and megafossils plant were found.On the basis of the above works,a stratigraphic unit "the Xiaguan Formation" of the formation level was established and used to carry out the stratigraphic subdivision and correlation.This discovery indicates the geologic age of the Xiaguan Formation may be the early-middle Late Cretaceous,and most possibly to be the middle-late Turonian to the middle Campanian.
