Scientific Classification
  Kingdom Animalia

  Class Sauropsida
  Superorder Dinosauria
  Order Saurischia
  Suborder Sauropodomorpha
  Infraorder Prosauropoda
  Family Riojasauridae
  Genus Riojasaurus
Riojasaurus was a herbivore (plant-eater) that lived in South America during the late Triassic period, about 225 to 219 million years ago. The name means "Rioja lizard" and was chosen because the first specimen was found in the La Rioja Province of Argentina.

Riojasaurus was about to 33 feet (10 meters) long. It had a heavy body and bulky legs, as well as a long neck and tail. The structure of the animal's skeleton suggests that it always walked on all four legs (relatively unusual for an early dinosaur), although it could probably rear up on its hind legs.
