Named By: José Bonaparte - 1991.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Abelisauria, Noasauridae.
Species: V. unicus (type).
Size: Tibia 14 centimetres long. Total length roughly estimated about 1.2 to 1.5 meters long.
Known locations: Argentina, Patagonia - Bajo de la Carpa Formation.
Time period: Santonian of the Cretaceous.
Fossil representation: Holotype partial leg and foot, additional limb remains now attributed to the genus.
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
is currently considered to be a noasaurid dinosaur, and a
particularly close relative of Masiakasaurus
Velocisaurus should not be confused with Velociraptor, a small but famous genus of dromaeosaur that lived on the other side of the world.
