Dinosaurus Punah Diduga Bukan Cuma karena Meteor, Apa Lagi?

"Dinosaur Extinction Suspected Not Only Because of Meteor, What Else?"

Dinosaurus Punah Diduga Bukan Cuma karena Meteor, Apa Lagi?

Dream - Dinosaur is an ancient animal believed by the community to be extinct due to a meteor strike 66 million years ago. However, experts have stated that this statement is not yet valid.

"Extinction of Dinosaurs"

For years, scientists have been debating whether meteorites are the main reason for the most recorded mass extinction in history, or if there are other natural factors that also play a role. It has been about 66 million years since dinosaurs disappeared from Earth's civilization, and many may blame the explosive collision of asteroids.

Other Factors that Cause the Extinction of Dinosaurs

However, a recent study states that there are other factors that contribute to the extinction of dinosaurs.

Quoted from usatoday.com, another factor causing the extinction of dinosaurs is volcanic eruptions. International group of researchers claim that the Earth's climate at that time was also unfriendly due to high sulfur levels, which also contributed to their extinction. The global temperature drop worldwide created unfavorable conditions for life.

"Our research shows that the climate conditions are almost certainly unstable, with repeated volcanic winters that can last for decades, before the extinction of dinosaurs."
"revealed study co-author Din Baker, a geology expert at McGill University."

He also added, his research with these experts was conducted to uncover the reasons for significant extinction as well as the factors that led to the emergence of mammals and the evolution of species like humans.

However, this study is still a subject of debate among scientists. About 75% of life on Earth, including dinosaurs, became extinct and marked the end of the Cretaceous period. This is why the question became the reason for experts to conduct research in the highlands of West India. This vast and rugged place, formed by molten lava, became the location where scientists hammered rocks and collected samples.

The analysis is aimed at estimating the amount of sulfur and fluorine emitted by volcanic eruptions into the atmosphere 200,000 years before the extinction of dinosaurs.

"Winter Volcanic Season"

The researchers said, quite a lot of sulfur was released that could trigger a steep decline in global temperature or volcanic winter. They measured the percentage of sulfur in the rock formations at that time and how much was pumped into the atmosphere in the chemical process. Din Baker described this event as cooking pasta.

"You boil the water, add salt, then the pasta. Some salt from the water gets into the pasta, but not much,"

"tuturnya." in English is "he/she said."

The concept is similar to how some elements are trapped in cooling minerals after a volcanic eruption. Then experts calculate sulfur and fluorine in rock samples, just like the concentration of salt in boiling water that can be measured by analyzing the pasta while cooking.
