Velocisaurus

Velocisaurus ("swift lizard") is a genus of noasaurid theropod dinosaur from the Late Cretaceous period of Argentina.

== Description == thumb|Size of Velocisaurus compared to a human Velocisaurus was probably around long, based on a tibia length of . This makes it the smallest noasaurid, after Berthasaura. The foot is unique in that the middle (third) metatarsal has become the main weight-bearing element. Its upper end has thickened whereas the shafts of the adjoining second and fourth metatarsals have thinned considerably. Such a configuration is unknown for other theropods, including birds. Bonaparte explained it as an adaptation for a cursorial (running) lifestyle. The high speed would have been necessary to escape larger theropods; Bonaparte suggested that Velocisaurus was itself an omnivore, as indicated by the fact that the sole claw found, of the fourth toe, was not trenchant but relatively straight.
