Sauropods

Sauropods were the long-necked, long-tailed plant-eaters, the largest animals ever to walk on land. They stood on four pillar-like legs and used their necks to reach food over a wide area without moving their huge bodies.

They were widespread by the Early Jurassic and lasted to the end of the Cretaceous. Famous members include Brachiosaurus, Diplodocus and Brontosaurus from the Jurassic, and titanosaurs such as Argentinosaurus and Patagotitan, among the heaviest land animals known.
