When did the dinosaurs die and how?

Answer 1

The dinosaurs died probably 65 million years ago. There are many different suggestions as to why they died out. Most scientists think that a massive change in the atmospheric system including a cloud of dust probably created by a volcanic eruption, and that was probably created by a 5 mile long asteroid that headed for earth 65 million years ago! and i mean this is the best answer you could get.

Those were just theories, but now scientists have discovered a huge crater that is expected to have been formed 65 million years ago. The shock wave it created is believed to have been powerful enough to wipe out most life in it's radius. Considering that the land on earth was very close together at the time, it is easily understandable why there are so many fish that seemed to have survived that blast.

Answer 2

Our best understanding at this point is that a small asteroid or large comet, something about 10 miles in diameter, slammed into the Earth near what is now the Yucatan Peninsula in Mexico, about 65 million years ago. Before that time, there were large numbers of dinosaur varieties; after that, there do not appear to be any large land animals. The shock wave, the fireball and the worldwide tsunamis killed about 75% of all life on the Earth.

We do still have some of the descendants of dinosaurs; we believe that the small surviving dinosaurs have evolved, over the ages, into birds. So every time you eat a chicken, you're having a distant ancestor of the dinosaurs for dinner!
