Sinosaurus (meaning "Chinese lizard") is an extinct genus of basal theropod dinosaur which lived during the Early Jurassic (Hettangian-Sinemurian). Fossils of the animal have been found in the Lufeng Formation, in the Yunnan Province of China. The type species, S. triassicus, was named by Chung Chieng Young in 1940. A second species, S. sinensis, was originally assigned to Dilophosaurus, but was later reassigned to Sinosaurus. Sinosaurus is morphologically similar to Dilophosaurus including the presence of a similarly shaped cranial crest, though its precise taxonomic position is uncertain, and the two genera may not be closely related.
