==Discovery and species== In April 1923, H. C. T'an discovered the remains in the east of Shandong at the village of Ch'ing-kang-kou, ten kilometres southeast of Lai Yang. In October of the same year they were excavated by Tan's associate, the Austrian paleontologist Otto Zdansky. Although the specimen was originally rather complete, only parts could be salvaged. The holotype, PMU R.240, was recovered from the Jiangjunding Formation of the Wangshi Series dating from the Campanian. It consists of the back of the skull, which was flat and elongated.
