> What killed off the dinosaurs? Was it one thing or a combination of things over time? Lately I have been thinking about this topic. I have formed a few conclusions.
> 1. The dinosaurs went extinct because if a series of events that lead to their down fall.
> 2. When the planet exploded between Mars and Jupiter sending astroids into our planet got the process started. (It exploded because of a commit collided with it. It also cause the atmosphere on Mars to rapidly dissipate. Cause planetary extension on Mars.)
> 3. Earth then captured a second moon that caused an increase in gravity. The second moon then collided into and formed the large moon we have know. The the moons collided it started the moon on a journey away from our planet.
> 4. The remain part of the exploded planet became Venus. A new planet this close to us increased the gravitonal pull on earth.
> 5. We are loosing our atmosphere and larger animals could not live with less oxygen.
> 6. The earth spun faster creating a lift like affect reducing the gravity on earth allowing larger animals. Less gravity affect larger the animal.
> 7. The magnetic field was much stronger.
> 8. May of the larger dinosaurs evolved into modern species like reptiles , frogs, amphibians and birds.
