Dinosaur extinction. Computer enhanced image depicting the extinction of the dinosaurs. A Gasosaurus constructus dinosaur skeleton is seen with a falling comet or meteorite. Dinosaurs became extinct about 65 million years ago at the end of the Cretaceous period. Their disappearance has been partly blamed on a comet or meteorite striking Earth. This event is known as the "K/T impact" because debris from it forms a boundary in sediments between the Cretaceous (K) and Tertiary (T) geological periods. The K/T impact would have thrown large amounts of debris into the atmosphere,blocking the warmth of the Sun and altering the global climate | |
