The word Dinosaur, itself, translates into "terrible lizard" in the Greek Language. Dinosaurs are thought to have roamed the Earth until about sixty-five million years ago when a mass planet extinction event is thought to have occurred. The most commonly accepted theory is that a massive asteroid plunged to Earth kicking up enough dust and rubbish to block the Sun light from reaching the Earth's surface. This complete lack of sunlight resulted in a huge change of the planet's ecosystem.
