ANATOMY
Riojasaurus was a massive quadrupedal (walked on four legs) herbivore. It was a about 30-36 feet (9-11 m) long and was heavily built. It had a long neck, a long tail, a small head, a long, bulky body, and thick, elephant-like legs with claws. The back legs were only slightly larger than the front legs. Its limb bones were solid and thick, but its backbone was hollow. It had spoon-shaped, serrated teeth.
DIET
Riojasaurus was an herbivore, a plant eater. Given its leg and ankle structure, it probably couldn't rear up on its back legs to graze or run.
INTELLIGENCE
Riojasaurus was a sauropodomorpha, whose intelligence (as measured by its relative brain to body weight, or EQ) was the lowest among the dinosaurs.
An almost complete Riojasaurus skeleton was found in northwest Argentina, in La Rioja Province. It was named by the Argentinian paleontologist José F. Bonaparte in 1969.
CLASSIFICATION
Riojasaurus was a Saurischian dinosaur, the order of lizard-hipped dinosaurs. It was a sauropodomorph (large, long-necked herbivores) and perhaps a melanorosaurid (the largest prosauropods; quadrupedal, thick-limbed herbivores). The type species is R. incertus (Bonaparte, 1969).
