Eye-opening study suggests dinosaurs weren’t wiped out by meteorite impact
The reason why the dinosaurs became extinct from our planet remains a mystery. about the fact there is only theoryyes and that of a meteorite that fell 64 million years ago on what is now Yucatan (Mexico)seemed to be the most solid thing about it.
However, like any theory, its veracity is debatable. What happens with this meteorite from 64 million years ago, is that even the crater (of Chicxulub) is in Mexican territory and evidence like that is hard to ignore.
But that’s what science has. There may be something very obvious that distracts you from reality and that is why you always have to look and analyze all the possibilities.
This was precisely what a renowned organization that brings together scientists from around the world did. Is named Proceedings of the National Academy of Sciences (PNAS) and they have recently published a study suggesting that the dinosaurs were not wiped out by a meteorite impact on Earth.
So what killed the dinosaurs?
Analyzing the history of the world in which we live, from as far back in time as can be reached to the present day, scientists find that five catastrophic events have been recorded that ended life on the planet.
According to the explanation of the PNAS scientists, according to Gizmodo, these have occurred due to two possible situations. One is that meteorites fell on Earth and the other is that there was a massive eruption of volcanoes.
The details to know which of the two occurred are in the study of soils. Each element in the rocks is a message that tells scientists what happened there.
So, by taking the guesswork out of studies and theories, scientists find less room for error in the suggestion that a massive eruption wiped out the dinosaurs.
The meteorite thing is still possible. But the percentage of massive volcanic activity is much higher.
“Our results make it very difficult to ignore the role volcanism played in these extinctions,” said Professor Brenhin Keller, one of the study’s authors.
Professor Keller says that these devastating eruptions are called basalt floods. These events are capable of covering about 100,000 cubic kilometers of lava. Gizmodo compares it to the 1980 Mount Saint Helens eruption. It was pretty disastrous and only covered 1 cubic kilometer.
This intense activity plays a fundamental role in the development of life as we know it. When they occur they modify the quality of the air. It is as if they cut off our oxygen for an indefinite period of time; simply the beings that inhabit the world die suffocated.
