  Reading the Farlow and Smith studies, and from what I know of
discussions on the tracksite, this was posited not as the animal kicking,
but "hopping" to reset stride, presumably because the predator had
"engaged" the sauropod assault-style. It need do nothing so much with that
leg but to simply not put it down. Apparently, birds and crocs will do the
same thing when accelerating. Jim Farlow say: "More to come..." :) His
study (soooo many lines of evidence) is only now, as he wrote, being
finalized on paper.

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
