Chingkankousaurus

Chingkankousaurus is a genus of theropod dinosaur containing the single species Chingkankousaurus fragilis. C. fragilis is known only from a single fossilized bone fragment from the late Cretaceous Period Wangshi Series of Shandong province in eastern China.

Description

Chingkankousaurus was identified by Yang Zhongjian 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. thought the scapula may have belonged to a tyrannosaurid. Chure 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, though it is currently considered a nomen dubium among that group.
