Sarcosaurus (meaning "flesh lizard") is a genus of theropod dinosaur, either a coelophysoid or a basal ceratosaur, roughly 3.5 meters long. It lived during the Sinemurian stage of the Early Jurassic, about 194 million years ago. Fossils of Sarcosaurus were found in the Lower Lias of England. The type species, Sarcosaurus woodi, was first described by Charles William Andrews in 1921 shortly after a partial skeleton had been found by S.L. Wood near Barrow-on-Soar.
