Chingkankousaurus (named for the Ch'ing-kang-kou (Chinese: 金刚口) village) is a genus of theropod dinosaur containing the single species Chingkankousaurus fragilis. C. fragilis is known only from a single fossilized bone fragment (specimen number IVPP V636) from the late Cretaceous Period Wangshi Series of Shandong province in eastern China. It was identified by Yang Zhongjian (C.C. Young) in 1958 from a single "scapula", which he said "basically resembles that of Allosaurus but is smaller." Molnar et al. (1990) thought the scapula may have belonged to a tyrannosaurid. However, the piece of bone Young thought to be a scapula was in actuality a piece of rib. Chure (2001) assigned it to the Coelurosauria, and more recent research has supported the initial identification as a type of tyrannosauroid, though it is currently considered a nomen dubium among that group.[1]
