Dinosaurs have been extinct for millions of year, but they continue to fascinate us because of their massive size, the funky headgear of a Triceratops and Stegosaurus and the huge teeth and ferocity of a Tyrannosaurus Rex. After studying the DNA in the water of Loch Ness in Scotland, scientists have just claimed that the Loch Ness monster thought to be a lost dinosaur, may actually be a giant eel but it does not stop the believers who flock to Scotland in an effort to catch a glimpse of a dinosaur. Perhaps the fact that they are extinct makes them a touch safer to approach and study. Who has not looked at an elephant and thought, "ok, big daddy, there used to be dinosaurs that were a lot bigger than you and thank goodness they are dead." We are also fascinated by dinosaurs because we fear that the same death-by-asteroid awaits us. The most credible theory of the mass extinction of the dinosaurs is that a giant asteroid hit the earth and caused a cloud of dust blocking out the sun that killed off the plants and led to a slow, hungry death for the dinosaurs on the other side of the world which were not killed on impact. Recently other theories have seen the light that looked at the slower effect of climate change that is believed to have caused the extinction of the ichthyosaurs, a fish-like reptile that vanished before the mass extinction of dinosaurs. But now scientists have found new evidence of the asteroid in the Gulf of Mexico which supports the theory that it caused a sudden mass extinction of the dinosaurs and as Robert Lee Hotz writes in the Wall Street Journal, it includes minute by minute evidence of what had happened to the earth the moments after the asteroid hit our blue planet. He also examines whether we could meet the same fate. – Linda van Tilburg
