According to scientists, a mass extinction 233 million years ago reshaped life on Earth, giving dinosaurs a chance to take over.
Named the Carnian Pluvial episode, the event is said to have been caused by a sudden change in climate.
1 A team of 17 scientists reviewed geological and paleontological evidence and found that huge volcanic eruptions occurred in the west. Canada Probably the most likely cause of the incident.
The eruption caused large amounts of volcanic basalt rock to flow, and it now forms the west coast of North America.
Climate warming was associated with an increase in precipitation – it was first identified by geologists in the 1980s as a wet period for a million years.
Despite the fact that huge parts of life were wiped out both at sea and on land, the event allowed dinosaurs to occupy the planet – they existed 20 million years ago but were rare and unimportant.
The researchers added that the event created a more modern ecosystem that was formed by coniferous forests, as well as some of the first mammals – turtles, crocodiles and lizards on display – and varied during this time.
Professor Jacopo Dal Corso, from GOCScience, University of China UhanHe said: “The explosions were so huge, they emitted large amounts of greenhouse gases like carbon dioxide, and there was a spike in global warming.”
He explained that five significant mass extinctions have been identified over 500 million years of history, all of which he said had “profound effects on the evolution of the earth and life.”
He added: “We have identified another great extinction event and obviously it has played an important role in restoring life on land and in the oceans and identifying the origins of modern ecosystems.”
Researchers further suggest that the Carnian Pluvial episode influenced marine life, seeing the beginnings of modern-style coral walls, as well as many modern groups of plankton.
