ANATOMY
Zigongosaurus was a large quadrupedal (walked on four legs) herbivore. It was a about 35 feet (10.7 m) long and may have weighed about 20 tons. It had a long neck, a long tail, a small head with spoon-shaped teeth, and thick, elephant-like legs.

WHEN ZIGONGOSAURUS LIVED
Zigongosaurus lived during the late Jurassic period.

DIET
Zigongosaurus was an herbivore, a plant eater. It stripped foliage with spoon-shaped teeth.

INTELLIGENCE
It used to be thought that the sauropods (like Zigongosaurus, Brachiosaurus and Apatosaurus) and Stegosaurus had a second brain. Paleontologists now think that what they thought was a second brain was just an enlargement in the spinal cord in the hip area. This enlargement was larger than the animal's tiny brain.

Zigongosaurus was a sauropodomorpha, whose intelligence (as measured by its relative brain to body weight, or EQ) was the lowest among the dinosaurs.
