Riojasaurus

Restoration of Riojasaurus

Riojasaurus ("Rioja lizard") is a sauropodomorph dinosaur of Late Triassic Argentina.

DescriptionEdit

Riojasaurus is large for a prosauropod, growing to about 10 meters in length. It was especially bulky, and had heavy legs, which meant it was probably quadrupedal.[1]

ClassificationEdit

Riojasaurus has been considered a close relative of the earliest sauropods. However, this is possibly due to convergent evolution.[2]

HistoryEdit

Riojasaurus was described in 1967 by José Bonaparte from the Los Colorados Formation of Argentina.[3]
