Yang Zhongjian
"Chingkankousaurus" 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." 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 (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.
