Same person. Doing a project. How did the dinosaurs get killed/destroyed? Thanx.
They ate each other? That's a new one.
It has been generally accepted by almost everyone that matters at this point that the Yucatan asteroid was responsible for the mass extinction that killed the dinosaurs (and nearly everything else). The most credible opponents to that theory are not suggesting that it wasn't an asteroid impact but that it was a second, later asteroid that did it.
Here are some articles for your research:

really there are more that two choices there is three. 1. A meteorite 2. The Great flood cause by God (depends on what you belive with that one) 3. The Ice Age
I believe it was a meteor. maybe there were some volcanbic eruptions too, but these may not have occurred at the time of any life
They ate eachother and eventually ran out of food also the ice age is another thing that they think could of caused it
lol. See mikeh's answer. I lolled at they ate each other. They must have been really hungry. haha.
