Fossil representation: Holotype partial leg and foot, additional limb remains now attributed to the genus.

       Though only named from a leg and foot,‭ ‬Velocisaurus seems to have been a particularly fast running dinosaur given that the leg shows clear adaptations for‭ ‬running,‭ ‬hence the name which means‭ ‘‬swift lizard‭’‬.‭ ‬When the dinosaur Velocisaurus was first described by José Bonaparte in‭ ‬1991‭ ‬he speculated that Velocisaurus might have been omnivorous given that the only claw found was straight,‭ ‬and not shaped like that seen in a meat eating theropod dinosaur.‭ ‬This might indicate that Velocisaurus was not running after other dinosaurs to eat,‭ ‬however without a skull and ideally confirmed stomach contents,‭ ‬the exact diet of Velocisaurus can only be guessed at.‭ ‬Velocisaurus is currently considered to be a noasaurid dinosaur,‭ ‬and a particularly close relative of Masiakasaurus from Madagascar.
       Velocisaurus should not be confused with Velociraptor,‭ ‬a small but famous genus of dromaeosaur that lived on the other side of the world.
