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?</text></comment>

How did they manage to feed themselves? Were they living sparsely? Was bioshpere denser then? Were they capable of eating just about anything?&lt;p&gt;And how was such massive size selected for? Is it just a matter of warmer climate and a feedback loop with larger and larger predators?</text></comment>
