Does anyone else here ever wonder if some of these "new" dinosaurs are really just re-discoveries of known dinosaurs? The article even mentions that the skeletal remains are incomplete. What if a number of these sauropods are really all the same species, albeit at different stages of their life? Is size alone enough to create a new classification? Perhaps growth continued throughout the life of a sauropod, and the largest ones were just the oldest?
