I have a thought on that very subject. Sauropods did not have to get the blood
there in the first place, it was there before they raised their body and neck
into the trees, the valves in the veins kept it from migrating back down the 
neck
and since there are few muscles in the neck (proof that they couldn't raise it
above their shoulders) did not have to feed the muscles that might have been
there. However the blood that remained in the head region could have been
oxygenated by the mere act of breathing since the nostrils were placed in such
proximity to the braincase and the nasal cavities passing directly to both sides
of the braincase there was no need to bring the blood up to the brain as it was
oxygenated from the passage of air over the nasal membranes and hence to the
brain cavity. Just as cocaine does or phenylephrine HCl.
does. The passage of air over the membranes would act as the pump for the
circulation, inhale and exhale would apply pressure to the passage. The
transition from one to the other would release the pressure. Hence no need to 
get
blood up to the brain against all of that fluid head cause it was already there
and circulation provided for. Why have your nostrils at the top of your head if
not for feeding your brain?
