Palaeontologist are still not sure why dinosaurs became extinct. The most popular theory is that "a meteorite hit the Earth, covering it in a thick cloud of dust. This blocked the sun, and caused huge changes to the environment to which the dinosaurs were unable to adjust."
So what it says is that the environment changed. I heard that the world was called Pangaea during the time the world started to spilt apart and I reckon that the meteorite started to make the earth separate...
We are lucky any way that the dinosaurs are not alive now!
THE END !!!
