The cause of dinosaurs extinction

Active volcanoes are the cause of the extinction of dinosaurs, not the meteorite that we had previously thought.

>>>Extinct dinosaurs are not just meteorites

10,000 years ago, lava flows from the Deccan Traps, a volcanic region near Mumbai, India, now release large amounts of sulfur and carbon dioxide into the air, causing catastrophic destruction by causing the earth to heat. up and acidified ocean.

This finding was presented at the annual meeting of the American Geological Society, contributing to the long-standing voice and debate over the cause of the dinosaurs extinction 65 million years ago.

The theory of Alvarez previously suggested that a large meteorite fell to Chicxulub, Mexico, about 65 million years ago, releasing large amounts of dust and toxic gas into the air, covering the sun, making the earth cold. Price, destroy dinosaurs and poison the sea creatures. The collision can also cause active volcanoes, earthquakes and tsunamis.

In 2009, oil companies, when drilling off the east coast of India, discovered a lava-bearing sediment dating back several millennia, located 3.3 km below sea level.

Gerta Keller, a geologist at Princeton University, USA, and her colleagues discovered that the sediment contains a lot of fossils belonging to the KT Boundary period, when dinosaurs disappeared. This sediment layer contains lava layers from the Deccan Traps area.

Active volcanoes are the cause of the extinction of dinosaurs, not the meteorite that we once thought.

According to the fossil analysis, the number of plankton is smaller, smaller, the number of animal shells remaining in the lava layer is also less. This indicates that the organism must transform after the volcano is active. Most creatures gradually die. There is only one plankton known as Guemnilitria - which is found in many fossils.

Guembilitria may be the most common creature in the world when a large amount of sulfur gas spreads in the sea. This gas can combine with calcium, making marine species unable to take calcium to synthesize shells and bones.

At the same time, fossils in India also showed that a large number of trees and animals on the ground had disappeared. This shows that the volcanoes themselves caused or destroyed on both the ground and the sea.

The team also found evidence that raises doubts about the meteorite hypothesis that hit the Earth causing extinction.

'The meteorite collision cannot produce enough sulfur and carbon dioxide that we can observe on the rocks, so the meteorite impact could only make the genocide worse. "This is not the cause of this disaster," Ms. Keller said.
