Kaijiangosaurus lini
He Xinlu named Kaijiangosaurus for the Kai River (Kai-Jiang) and assigned it to Megalosauridae in 1984. Sadly, as of 2022, most of its remains have yet to be fully described (at least in English), and there's a growing suspicion in the scientific community that they may belong to at least two unrelated species.
Barring a shift to Carnosauria (Molnar, 1990), the bin (Rauhut, 2003), Tetanurae (Holtz, 2004), and possibly Averostra (Carrano, 2012), Kaijiangosaurus has barely had a mention in the literature since its initial description. Some experts suspect it may be synonymous with Gasosaurus from the same area.

(Lin's Kai River lizard)Etymology
Kaijiangosaurus is derived from "kaijiang" (Kai River), from the Chinese "kai" (open) and "Jiang" (river), and the Greek "sauros" (lizard).The species epithet, lini, honours Chinese palaeontologist Lin Wenqiu.
Discovery
Kaijiangosaurus was discovered in the Lower Shaximiao (aka Xiashaximiao) Formation, Sichuan Province, China.The holotype (CCG 20020) is a set of seven neck vertebrae.
Referred material includes a tooth, a cheek bone, two back and seven tail vertebrae, a partial shoulder girdle, arm bones (humerus and ulna), a partial hand, leg bones (femur, partial tibia, fibula) and a partial foot. Unfortunately, it is not clear whether they collectively represent a single taxon.
