@john Fantastic picture, Liked how much it drew you in, almost like a real still existing world.

@john I hope we'll get to the bottom of the BYU 9024. It's been jumping back and forth between Supersaurus and Barosaurus.

@john how could that guy even move?? Looks like he’d topple over forwards if he tried to walk

@ednazzaro That's a good question, and it's one I have the answer to!Sauropod necks look huge, but actually only make up a small proportion of their bodyweight. They are considerably narrower than the body, and are filled with air-sacs (like birds). Their tails which counterbalance, on the other hand, are more solid and contain massive muscles.The centre of gravity in this sort of sauropod (diplodocid) is actually really close to the hips.@mike wanna add anything?

@john @mike That makes sense. They’re just so foreign-looking to anything around today it’s sometimes hard to believe they were real. I’ve seen depictions of them standing on their hind legs which fits in with what you said as well. Must’ve been quite a sight to see!

@ednazzaro @mike Yep, I'm in the camp that thinks they were actually specially adapted to do just that. Sauropod anatomy is probably my favourite bit of dinosaur palaeontology. Even simple questions about them lead you down rabbit holes of, well, how does any of this work?

@john That's all solid reasoning. BUT I have to admit that even I thought John had made that neck a bit of a Fat Boi. I can only assume it's much much narrowed side-to-side, and we're mostly seeing soft=tissue flaps hanging down or suspended from ligament.

@mike I think it's pretty much traced from a @ScottHartman skeletal, so any faults are entirely his.

@john @mikeas you both know from past SVPOW posts that all sauropod neck reconstructions are actually skinny boys relative to tissue depth in living birds. The taller-but-narrow muscle and ligaments in the back half of sauropod necks are probably necessary for them to be raised up, and are consistent with birds that have bifurcated neural spines.
