Description

Chingkankousaurus was identified by Yang Zhongjian (C.C. Young) in 1958 from a single "scapula",^[1] which he said "basically resembles that of Allosaurus but is smaller." It had been proposed that the scapula was a rib or gastralia fragment, but this was considered unlikely in a 2013 study. Molnar et al. (1990) thought the scapula may have belonged to a tyrannosaurid. Chure (2000) assigned it to the Coelurosauria, and more recent research has supported the initial identification as a type of tyrannosauroid, with some even arguing it to be a synonym of Tarbosaurus bataar,^[3] though it is currently considered a nomen dubium among that group.^[2]
