the argument with the dino flyers is this; that it was previously thought that these flying beasts would have to be cliff dwellers (so they could fall of the cliff and glide), but some scientists are now arguing that many of these dino's were not cliff dwellers (ill find this info), which raises the question of how would they take off under such gravity as ours. they would either need long stilk like legs to get a running start or less gravity. see, a 40, 50 or even 60 foot wing span on this beast would prohibit it from flapping while grounded; his "arm" bones would surly break... would be impossible unless they were 1. all cliff dwellers or 2. had long quick legs to run or 3. much less gravity where takeoff would be achieved with very minimal wing flappage (or hopping into the air). i will come back to this............

still looking for the best links on this kundalini. i will post them.....
