The Sauropod is one of the most commonly depicted dinosaurs, characterised by its large size, long neck and tail, a four-legged stance, and a herbivorous diet. It is the largest of all dinosaurs and largest of all the land animals that ever lived. Its long neck enabled it to take foliage from even the tallest trees, in somewhat the same manner as modern giraffes do.
By the Late Jurassic (150 million years ago), sauropods had become widespread. However, as with all other non-avian dinosaurs alive at the time, they died out in the Cretaceous–Paleogene extinction event. Fossilised remains of sauropods have been found on every continent, including Antarctica. Complete sauropod fossil finds are rare. Many species, especially the largest, are known only from isolated and disarticulated bones.
