Most recognizable member of the sauropod family with heavy body, elephantine legs and feet, and long neck and tail

The Apatosaurus (formerly called brontosaurus) is the most recognizable member of the sauropod family of dinosaurs, which have heavy bodies, elephantine legs and feet, and long necks and tails. They are plant-eaters who live in small family groups, and are normally peaceful if not threatened. However, their sheer bulk makes them formidable opponents if aroused.

Jurassic herbivore, once called brontosaurus

Large quadrupedal herbivores with elephantine bodies and extremely long necks and tails, the sauropods are herd animals. They can bite, but are only really dangerous when they trample. Trampling automatically kills any creature weighing less than a ton in their path—saving throw vs death to avoid. A whole herd stampeding is an impressive sight, best viewed from a safe distance. In fantasy gaming environments sauropods might make good meat animals or beasts of burden.
