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. ;) )
