HOw did the dinosurs all die?

Answer 1

The short answer is they don't know. No one knows for sure, but, there are many theories about how they died off. They run from the passable, like a giant asteroid hitting the Gulf of Mexico or the Pacific ocean, To the wild and unlikely, like a alian space craft carried in a new disease and killed off every thing.
Some believe they were not killed off at all, just evolved into modern animals, Like birds, Gators and such. There are many ways they could have died off. Mostly connected with the environment. Like a volcano exploded and filled the air with smoke and ash, which cased the temperature to drop and kill the plants which were the primary food source.
The only thing science knows is that it happened, But, No one can say they know how or even why???????

Hope this helps,
