It is unlikely that a predator could bring down an adult sauropod because of its huge size. However, the young sauropods may have been more at risk.
Sauropods such as Diplodocus had a large claw on the front foot, and were probably able to rear up and use this claw to defend themselves. Some scientists believe that they could swing their huge long tail as a weapon. It would have struck the attacker with great force, like an enormous whip.
