Brachiosauridae is a family of sauropod dinosaurs belonging to Titanosauriformes. They were herbivorous quadrupeds with longer forelegs than hind legs, the name derives from the Greek for arm lizard - and long necks. Despite their apparently distinctive features, there is some dispute as to whether Brachiosauridae is really a distinct family or a collection of basal Titanosauriformes. As a result, there is also some dispute about which animals belong within this family.
