Dino Land Paleontology  and Prehistoric Planet interviews with Matt Wedel discuss some of the following questions.  For more information also see Titanosaur Notes

Could sauropods rear up on their hind legs for feeding?

How did sauropods feed?  With vertical necks like giraffes or with the head held horizontally?

How did sauropods pump blood to their heads if they reared up or held their heads high to feed?

Could dinosaurs have used their long necks as snorkels while in the water?
