What killed the dinosaurs? New studies suggest volcanoes not killer asteroid responsible | Science | News



Millions of years before humanity passed on Earth, dinosaurs ruled the world. It is generally accepted that the death of dinosaurs was caused by a massive asteroid, which hit the Earth 66 million years ago. But a couple of new landmark studies have shown that a huge volcanic eruption contributed to the extinction of gigantic prehistoric reptiles. according to innovative new research that unravels the mystery of how dinosaurs have been destroyed from the face of the Earth after they have gone on Earth for millions of years

An asteroid mass extinction event may be the most famous of massive extinctions [19659002] While the opening of the Chikslub crater in the Caribbean confirmed the impact of a huge asteroid, a sealed fate of dinosaurs. SKY: NASA in extraterrestrial life UNLOCKED after iscovery DNA

In some locations more than 2 kilometers thick, these campsites in India show massive volcanic eruptions in India.

Using uranium and lead in hardened magma minerals, scientists discovered four huge volcanic events that began tens of thousands of years before the asteroid.

Each lasted about 1

00 thousand years, these explosions throw out incredible quantities of climate change greenhouse gases, and probably lead to the first wave of mass extinction.

These new results were released along with other modern studies that came with a slightly different conclusion

Their dating of the basaltic rocks of the Dean's apartments showed that most of the eruptions occurred after the arrival of the asteroid – possibly caused by super-earthquakes after exposure

However, Dr. Courtyne Spreene, a geologist at Liverpool University, who led the second study, said that this does not mean that volcanoes did not play any role in extinction. 19659004] More: NASA detects extraordinary new images of the Ultimate Thule asteroid

The smallest momentum of the eruption volume, "she explained.

The team assumed that instead of causing the gases to explode when volcanoes exploded, they gradually leaked in years b

Although the final answer to the question that the dinosaurs had been killed is still elusive, Dr. Spain and her colleagues argue that this was probably the result of "one-two strikes" from both volcanoes and asteroids.

The rapid warming of the Earth's climate can lead to the fact that the remaining creatures adapted to life in hot conditions, and then faced with rapid cooling after the dust was polluted by the sun from the impact of the asteroid
