Scientists are constantly wondering about what caused the end of the dinosaurs. A new theory has just made its appearance, that the earth and the sky would be united to lead to their loss, caused in fact by both an asteroid and volcanoes. For 35 years and up to now it was assumed that it was the fall of a gigantic meteorite there are 66 million years, which caused the mass extinction of all life on Earth, completely annihilating thereby dinosaurs. However, according to US geologists, is not the only cause. Significant volcanic eruptions due to this impact have they-also participated in this disappearance While this meteorite left a crater 180 km in diameter Chicxulub, in the Yucatan in Mexico and sent clouds of dust into the atmosphere, leading to the complete disruption of the climate, but this is not all. Major volcanic eruptions on the Deccan plateau basalt in India before and after the fall, according to the geologists would be the real cause of this disappearance, making the consequences of the impact of the meteorite negligible. The two hypotheses are thus reconciled, since the scientists found that in 50,000 years this impact, volcanic activity had increased dramatically, the flow of basaltic lava flows of the Deccan having doubled during this period. The combination of an asteroid impact and the increase in volcanic activity could have covered the Earth fumes and toxic dust, altering the climate and causing the extinction of many species, vegetable as animal. These effects have also delayed the re-emergence of animal and plant life for 500,000 years; according to Renne teacher, he also took a half a million years the oceans to find their original biodiversity. <- share buttons by mashshare.net - version: 2.4.4>
But who really killed the dinosaurs?
