re: bipedal apatosaurs & stegosaurs - tails for defense



There is no proof that diplodocids or stegosaurs used their tails for
defense against predators; these ideas are entirely supposition, and to
speak of them as fact is misleading. While this idea *might* work for
diplodocids, an aerial view of _Stegosaurus_ (see DINOSAURS PAST & PRESENT
- VOL. II, either Paul or Czerkas) will give you an idea of how difficult
it would be for that animal to keep an eye on a predator attacking from
behind. The rear is not the best place for armament, and stegosaur tail
spikes were probably used for other behavior than defense, possibly display
or courtship.
