It is known that dinosaurs, as well as a large proportion of organisms became extinct 66 million years ago (the end of the second and early third period between Cretaceous walbaliogin), but the discussion on the causes of extinction still rages 30 years ago.

There are two theories to explain this species:

The first returns because of extinction to a giant Meteor collision with Earth (there are crater resulting from a collision with the Chicxulub in Mexico 1) by about 300,000 years of the extinction of the dinosaurs, according to a study published in 2007, and is a great period makes it difficult to say that the collision was the cause of the disappearance.

The second theory, the event returns to heavy volcanic activity. But a new study published on 7 February in the scientific journal Science adopted Pau Renne and his University of California history higher res of rocks subjected to shock the Chicxulub meteor, revealed that the collision may have occurred before 66038000 years before 33,000 years of mass extinction of living organisms, it is clear that the collision might be the main cause of the extinction of these giant objects, but not the only one, and here the study indicates that a million years before the disaster marked by changes Great weather including low temperatures in some periods to between 6 and 8 degrees. These changes could be explained by extraordinary volcanic activity experienced by India which may be prepared for the extinction of dinosaurs through the imbalance of environmental regulations, and therefore the Meteor is the knockout.
