Science Breakthrough: New Mass Extinction Has Been Identified – Here’s What Caused It

Mass extinctions are not discovered too often – this is more than obvious. These are some events that have been so devastating that they stand out in the fossil record, according to the website

This extinction triggered the dinosaur takeover of the world 

They note that a new paper that’s just been published in Science Advances reveals that an international team found a major extinction of life 233 million years ago – this reportedly triggered the dinosaur takeover of the world.

The crisis has been called the Carnian Pluvial Episode.

The team included 17 researchers who have been led by Jacopo Dal Corso of the China University of Geosciences at Wuhan and Mike Benton of the University of Bristol’s School of Earth Sciences.

It’s been revealed that the team of experts reviewed all the geological and palaeontological evidence and determined what had happened.

The cause of the mass extinction 

The cause of this great disaster was probably around massive volcanic eruptions in the Wrangellia Province of western Canada.

“The eruptions peaked in the Carnian,” according to Jacopo Dal Corso.

He continued and said that “I was studying the geochemical signature of the eruptions a few years ago and identified some massive effects on the atmosphere worldwide. The eruptions were so huge, they pumped vast amounts of greenhouse gases like carbon dioxide, and there were spikes of global warming”.

This warming was associated with massive rainfall, and climate change caused huge biodiversity loss in both the ocean and on land. This led to the growth of plant life and the expansion of conifer forests. 

Besides dinosaurs, more groups of animals and plants appeared at that time: some of the first turtles, crocodiles, lizards, and the first mammals.

“So far, paleontologists had identified five “big” mass extinctions in the past 500 million years of the history of life,” according to Jacopo Dal Corso.
