*"V. unicus" Bonaparte, 1991 (type)

"Velocisaurus" ("swift lizard") is a genus of ceratosaurian dinosaur from the Cretaceous Period of Argentina. Known only from hind limb bones, it was probably around 1.2 meters long (4 ft). What is known of the hind leg and foot show adaptations for running, giving "Velocisaurus" its name. A study of theropod relationships by Novas and Apesteguia (2003) showed that "Velocisaurus" was a close relative of the strange ceratosaur "Masiakasaurus". These two may form a subfamily of noasaurids, the Velocisaurinae.
