Lukousaurus is an archosauromorph based on most of a small skull's snout, displaying distinctive lachrymal horns, found in the Early Jurassic-age Lower Lufeng Formation, Yunnan, China and was described by Chung Chien Young in 1940.

[2] At a locality in the town of Huangchiatien (also called Dahungtien) in Yunnan Province, China during the late 1930s, a partial anterior skull and lower jaws as well as possibly a tooth and humerus found nearby.

[3] Young noted that the skull is very strange, with morphologies similar to those of not just Coelurosaurs, which he thought the taxon was, but also Prosauropods and Carnosaurs.

[8] Dong Zhiming in his book on Chinese dinosaurs assigned Lukousaurus to Podokesauridae in 1992, a similar conclusion to Young's original classification with Podokesaurus, though in 1997 Kenneth Carpenter placed it as an indeterminate Theropod.

[9][10] In 2008, Mickey Mortimer believed that Lukousaurus was either an abelisaurid ceratosaur or a sphenosuchian, but revised her position in 2011 after placing it as a basal pseudosuchian using a phylogenetic matrix developed by Sterling Nesbitt.
