Hum, don't know.  Then again how intelegent were they, and how heavy were
their brains (or spinal cords in this case).  I'ld guess they were very
stupid, so they would need a preportionally smaller brain.  Where as an
elephant is fairly cleaver (say compared to a horse or something) so it
needed a preportionally bigger brain then a Bronto.  (Naturally I have
extensive field experence with dinosaurs.  ;)   )
