Sauropods

Sauropods (meaning "Lizard-Footed") were an infraorder of large, four-legged, herbivorous dinosaurs. They had very long necks, small heads with blunt teeth, a small brain, and long tails for counterbalancing their necks. They had large guts, which were necessary for digesting huge amounts of plant material. They walked relatively slowly on four short, thick, five-toed legs. Their nostrils were located on the upper parts of their skulls, sometimes very close to the eyes. A few of the later Sauropods had some body armor (e.g., Titanosauridae).
