Dinosaur extinction of the late Cretaceous is an enigma. A scorched earth layer was discovered at the end of the Cretaceous system from drilling cores in west of Nei Monggol in China. And there was a creature interruption.for 6-8 million years after that period through fossil analysis of the area and the adjacent area. Just in the same system of scorched earth layer, the Polish scientists found the abnormal geo chemical phenomena and high dense universal substances generally contained in meteorite. The authors think, at the end of Cretaceous, many celestial bodies ran into the earth. The collision caused fires all over the world and slowed down the speed of the earth rotation suddenly. The oxygen density decreased sharply. And because of the sudden increase of day length, the biological clock of dinosaur was in the state of chaos. That’s the reason why dinosaurs got extinct. It took a very long time both for the oxygen to return normal for most creatures to live and for the new species fit for new rotation speed of the earth to come into being. That’s why there was the creature interruption.after the extinction of the dinosaur.
