In which case, add a prehensile tip (oh no, you say, again with the
prehensile tails!) and there would be no need to raise the head
up very far. Just tear down a few branches with the tail and feed
on them from ground level. If diplodicid tails were physically
capable of bending when an animal reared up (for mating or particularly
high branches), then they must have had some degree of vertical
movement. In which case the long neck may be a secondary feature to
counterbalance the more important tail (just as Michael Crichton
mentions, presumably from a scientific source, in "The Lost World").
