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.[1] The generic name refers to the Lugou Bridge, lit. “crossroads”, near Beijing, where the Sino-Japanese War started.[1] L. yini is tentatively classified as a theropod dinosaur by some allied to ceratosaurs, by others a coelurosaur. Its skull is rather robust for its size though the teeth were described by the author as typically theropodan. It may, however, be a crurotarsan or a primitive crocodilian.[2] Whatever Lukousaurus was, it was definitely an archosauromorph.[3]

In either the late 1930s or in 1940, the front half of a fossilized skull, which became the holotype of Lukousaurus yini, was discovered in Dahungtien, China.[1]
