Most of the sauropods were too enormous to be successfully attacked by predators. Some of the smaller sauropods developed their own defences. Saltasaurus had body armour, while Shunasaurus had a tail club like the ankylosaurs. Shunasaurus was found in China. It was about 10 m long and weighed about 2.5 tonnes. Other sauropods could defend themselves adequately by using their enormous tail as a whip, wielded with enormous force. The largest sauropods would have reared up and trampled any predator with their front legs.
