Mass Destruction Occurred 6.6 Million Years Ago Even Oceans Were Also Affected

In an event of mass destruction caused by the meteorites shower on the earth 6.6 million years ago, many species of insects and animals were completely destroyed. During this time, the amount of sulfur in the earth’s atmosphere had increased, which made the oceans here more acidic. Researchers have claimed this in a new study.

Researchers from Yale University in the United States stated, “Millions of years ago, nearly three-quarters of the Earth’s flora and fauna had gone extinct due to a large amount of meteorites shower from space. Also, the sulfur gas released from these meteorites spread throughout the atmosphere, due to this reason the water of the oceans also became acidic.”

The study, published in the PNAS journal, states that ‘Cretaceous–Paleogene’, or mass destruction, is associated with the sharp drop in the ocean’s pH level, which further reinforces that seawater became acidic due to the same reason. Hundreds of creatures are believed to have been extinct from Earth after the Cretaceous-Paleogene. In subtle form, it is also known as the ‘K-PG extinction’.
