Can your guys think of other factors? As I think Tunguska event or Asteriod are the final event. Actually there is a drop of dinosaur species in the Montona of USA at about 7000 ma. So I think there could be other reason to make the number of species of dinosaur decrease in the final 500 millions years of dinosaur period. The collison of asteriod should is the final and the main disaster to kill the dinosaurs作者:
