Brachiosaurus was one of the tallest dinosaurs to have lived in North America and Africa. At 23 m in length it was also one of the longest. It was a sauropod and a herbivore, feeding most only foliage of Jurassic trees.
In Extreme Dinosaurs the model of Brachiosaurus from Walking with Dinosaurs was used to depict the sauropod dinosaurs in general, as opposed to Argentinosaurus, for which a Diplodocus WWD model was used instead. (152-144 MYA).
