Scientists say, dinosaurs became destroyed as a result of comet impact, not an asteroid

Space object which wiped out the dinosaurs 65 million years ago, it might be a comet impact, not an asteroid, a new study indicates.

180-kilometer Chicxulub crater, located in Mexico, was established as a result of the collision, which led to the extinction of the dinosaurs and about 70 percent of all species on earth, according to many scientists.



But in the new study, presented this week at the 44th Lunar and Planetary Conference, said that the culprit of this event could become a smaller, fast object, such as, for example, the comet.

After spending the new calculations, the researchers found that the amount of debris caused by the decline of the cosmic body was less than expected. This meant that the space object had to be less than previously anticipated. But to form a giant crater Chicxulub, the object was to move with the speed of a giant - so the scientists came to the conclusion that the object hit the ground was not an asteroid and a comet.
