Comment on Mischief-causing titanosaur by DrScottHartman
I find it absolutely the neck to body proportions absolutely mind boggling, especially on an animal this size. I would expect a longer tail for a counterbalance, and a LOT more musculature. Then again, somebody 200 million years in the future might say the same about giraffes. They have no tail at all for counterbalancing. Nature works in mysterious ways.
Yeah, there doesn't seem to be any correlation between neck and tail size - I think quadrupedal animals are under a bit less stress in terms of limitations due to imbalance.
Oops. *facepalm* I totally forgot to take into account that quadrupedal animals would require less in terms of a counterbalance. Still, the size of the neck is totally crazy. I remember reading a theory in either the book Jurassic Park or The Lost World that said that sauropods would have had to keep their heads close to the ground most of the time.
The cervical air sacks probably improved their balance as well - at least that's what I tell myself whenever I see a sauropod skeletal and instinctively expect it to fall flat on it's face 
Did dinos have cervical air sacs? Excuse my ignorance, as I'm not that well versed in dinosaur anatomy. Before today, I had no idea what a cervical air sac was.
In that case, seek out the sauropod enamoured bloggers of SV-POW. They've been writing about this stuff for ages and their tutorial on pneumaticity from 2007 is an excellent place to start [link]
Thanks, it was an interesting read.
