What was the largest dinosaur? And how did it get so big? If you're shouting 'Diplodocus!' and 'Brachiosaurus!', you're on the right track.

Sauropods such as these were enormous. But the true champions were the titanosaurs, the last-surviving group of long-necked sauropods. Titanosaurs such as Puertasaurus, Patagotitan and Argentinosaurus were the longest and heaviest dinosaurs of them all. In fact, they were by far the largest animals to ever live on land.

Watch our animation to find out how these dinosaurs were able to grow so big and what this meant for their survival.
