This hypothesis states that about 65 million years ago, a giant meteorite crashed into the the earth. The impact of the collision raised enough dust to block the sun's rays for many years. The earth probably became colder, plant life began to die, and many animal species, including dinosaurs, became extinct. As the dust settled over the earth, it formed a layer of iridium-laden rock.
