Fragment from this link:
"In 1980 a famous scientists named Luis Alvarez discovered that when the dinosaurs first began to disappear, rocks and fossils from all around the planet had a thick layer of iridium dust. Iridium is a metal, like iron or aluminum, and is present in large amounts on asteroids. From this finding, Alvarez guessed that a huge asteroid hit the earth 65 million years ago and caused the dinosaurs to go extinct. In the 1990's, paleontologists found the crater from this asteroid on the Yucatan peninsula in Mexico, and found rock fragments from this impact had been blown as far away as Nebraska! Judging from the amount of iridium dust and the size of the crater, Alvarez and other scientists guessed that huge amounts of dust and ash from the explosion were thrown into the sky and calculated that this blanket of soot would have blocked out the sun for many years."

Fragment from this link:
"65 million years ago a ten kilometer object hit the earth at the Yucatan peninsula in Mexico. This impact killed 90% of all life on the planet and created a thin layer of debris all over the planet. It was dark for six months and the oceans became somewhat toxic for a while. If this happened again today, civilization would be wiped out -probably no one would survive".

Fragment fro this link:
"While very small meteorites hit the Earth every day, the last big impact was 65 million years ago, when it is believed that a comet hit the Yucatan peninsula in Mexico. It caused enough damage to the environment to kill all the dinosaurs and many other kinds of animals. Such events seem to happen surprisingly regularly throughout the history of the Earth".
