New life through volcanic gases
He suspects that the volcanoes even ensured that new life could be created on Earth. This assumption is also supported by other studies that show that volcanic gases have altered the carbon cycle and have thus curbed global warming. Chiarenza believes cooling has been slowed by the asteroid impact. Plants in particular could have recovered, for example, and mammals would have increased in size and size.
The researchers also found evidence that dinosaurs survived previous massive volcanic eruptions in the Indian Deccan region. They therefore assume that the mass extinction was triggered by a sudden event – such as the asteroid.
criticism
The results of the study were published in the Proceedings magazine of the National Academy of Sciences. Chiarenza believes that the debate over the cause of mass extinction is not over. The first criticism comes, for example, from paleontologist Gerta Keller from Princeton University. The study ignored recent research on volcanism in the Deccan region. They would clearly point out that massive volcanic eruptions coincided with the mass extinction, she told the Guardian.
