The Day the Mesozoic Died

Once ago scientists believed that mesozoic era ended by very slow change overtime. But then a man thought otherwise. He thought they they all died in an instant by a giant meteor. Scientists wouldn't believe this catastrophic event. So he went out to prove them wrong. He eventually found a giant crater in Mexico. There him and his scientists found fossils of land and sea animals. You could just find them lying around all around the ground. He also found that rocks that could only be that way unless a catastrophic event happened. He proved those scientists wrong and today we believed that a meteor killed all the dinosaurs.
