A PRELIMINARY REPORT ON THE NEW DINOSAURIAN FAUNA FROM THE CRETACEOUS OF THE RUYANG BASIN, HENAN PROVINCE OF CENTRAL CHINA

A new dinosaur fauna, the Ruyang Gigantic Sauropod Dinosaurian Fauna from the early Late Cretaceous of the Ruyang Basin is named. The new dinosaurian fauna is dominated by large-sized sauropod dinosaurs, companying with theropod dinosaurs, such as omithomimid, oviraptorid, spinosaurid and carcharodontosaurid dinosaurs. Two new taxa are erected, they are a oviraptorid dinosaur Luoyanggia liudianensis gen. et sp. nov., and a sauropod Xianshanosaurus shijiagouensis gen et sp. nov. The dinosaur assemblage from the Ruyang Basin indicates that the dinosaur-bearing deposits are Cenomanian in age.
