| Velocisaurus unicus Bonaparte, 1991 |
Velocisaurus ("swift lizard") was a ceratosaurian dinosaur species from the Cretaceous Period of Argentina. Known only from hind limb bones, it was probably around 4 feet long. 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.
