What really killed the dinosaurs? New studies indicate that volcanoes may have played a role

The mass extermination event that killed the dinosaurs is generally believed to have been triggered by a massive asteroid that struck the earth 66 million years ago. However, a couple of new studies believe that a huge volcanic eruption may have played a role in the dinodom. Both studies, published in Science, look at the link between the impact on the Yucatan Peninsula in Mexico that may have triggered volcanic eruptions in India. In a paper, they were able to determine the exact dates of the outbreaks, and noted the "million-year outbreak" sent lava hundreds of miles across India, creating the river basalt in Deccan Traps. "Now that we have dated Deccan Traps lava floating on more and different places, we see that the transition seems to be the same everywhere," says UC Berkely's resident professor Paul Renne in a statement. "I would say with quite a lot of confidence that outbreaks occurred within 50,000 years, and maybe 30,000 years, of the effect, which means that they were synchronous within the margin of error."

The mass extermination event that killed the dinosaurs is generally believed to have been triggered by a massive asteroid that struck the earth 66 million years ago. However, a couple of new studies believe that a huge volcanic eruption may have played a role in the dinodom.

Both studies, published in Science, look at the link between the impact on the Yucatan Peninsula in Mexico that may have triggered volcanic eruptions in India. In a paper, they were able to determine the exact dates of the outbreaks, and noted the “million-year outbreak” sent lava hundreds of miles across India, creating the river basalt in Deccan Traps.

“Now that we have dated Deccan Traps lava floating on more and different places, we see that the transition seems to be the same everywhere,” says UC Berkely’s resident professor Paul Renne in a statement. “I would say with quite a lot of confidence that outbreaks occurred within 50,000 years, and maybe 30,000 years, of the effect, which means that they were synchronous within the margin of error.”

Perhaps even more amazing is that three quarters of the lava flow erupted after the impact, while previous studies said that 80 percent of the lava came before the impact.

The researchers were able to use the argon argon data method to measure the rocks to determine when the rocks were, building up previous research. Using the new method, they could enter a date of 66,052,000 years ago, “give or take 8000 years”.

Assuming that the majority of the lava came out after the impact, the gases that entered the atmosphere probably struck out over a long period of time, similar to what is seen with Mt. Etna in Italy and Popocatepetl in Mexico.

“We suggest it is very likely that many of the gases coming from the gastrointestinal tract before the outbreak, they do not necessarily correlate with outbreaks,” Renne said. In the event of the K-Pg eradication, the symptoms of significant climate change occurred before the peak at volcanic eruptions.

Courtney Sprain, the lead author of one of the studies, said the findings changed the role of the decane traps in the K-Pg extermination. also known as extinction that occurred at the end of the war.

“Either the Dean’s outbursts did not matter – which we think is unlikely – or many climate-modifying gases erupted during the lowest volume pulse of the outbreak,” Sprain said in the same statement.

A study published in January said the effect of the asteroid caused a worldwide tsunami that reached more than 5000 feet in the air.
