Re: Berlin Brachiosaurus

Are there any extant quads that are unable to swim? Armadillos have a rep 
locally as sinkers, but other than that nothing comes to mind. Which doesn't 
mean much, so I ask...

A paper a few years ago attempted to look at brachiosaur bouyancy, and
concluded that their relatively narrow bodies and their top-heaviness
may have made them too unstable (and prone to capsizing) for them to
swim in open water.
