a meat-eating noasaurid ceratosaurian theropod dinosaur from the Late Cretaceous of Argentina.
Neuquén province, Argentina
(Swift lizard with a unique foot)Etymology
is derived from the Latin "velocis" (swift) and the Greek "sauros" (lizard).
The species epithet
, means "unique" in Latin, referring to the ususual design of its foot.
The first remains of Velocisaurus
were discovered in the Bajo de la Carpa Formation at Boca del Sapo, Neuquén province, Patagonia, Argentina, by Oscar de Ferrariis and Zulma Brandoni de Gasparini in 1985.
(MUCPv 41) is the lower part of a right leg. The virtually complete left leg of a second specimen from the Bajo de la Carpa Formation at Paso Córdoba in Argentina's Río Negro Province was described in 2016, and confirmed that Velocisaurus
—with its very short, stout, and bowed thighs compared to very long and slender lower leg bones—really were swift lizards.
