The Wangshi Series is a late Cretaceous sedimentary rock formation found in Shandong and Jiangsu provinces in eastern China. It has been estimated as Campanian in age. Dinosaurs recovered include the large theropod Chingkankousaurus, which is possibly synonymous with Tarbosaurus, as well as herbivororous hadrosaurs Tanius, Shantungosaurus, and Tsintaosaurus.
