There has been a huge controversy over what actually killed off the massive population of the dinosaurs and other organisms they co-existed with. The myth came about when archeologists started discovering dinosaur fossils all around the world. The scientists don't know how or why they died and where they are now. Some people think it was an enormous asteroid (estimated 120 miles in diameter) smashing into the earth. Another theory is a massive volcanic eruption.
Scientists have estimated that the dinosaurs were walking on the earth about 65 million years ago. According to Dr. A. Buckley of Sothworth Planetarium, Maine, USA, he believes it was an enormous asteroid that struck the earth and killed the dinosaurs; he thinks this because the mineral iridium was found in the soil where the fossils were discovered. And iridium is only found in two places and one of those places is in outer space. The other place iridium is found is near the center of the Earth. That’s the reasoning behind why scientists think a massive volcanic eruption destroyed the Dinosaur’s thriving population. However, some scientists around the world think they still exists today. According to a video on 60 minutes they have reason to believe that they can regenerate a dinosaur through a chicken becuase both a chicken and a dinosaur have simliar qualities.
This myth or controversy is a worldwide question. Nobody is certain which of the two theories was the actual killer of the dinosaurs. At this point in time (2009) one single person can't be 100% positive on the cause of the mass extinction of so many dinosaurs and organisms 65 million years ago.
