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.
