Key Drivers Of Recurrent Extinction In The Triassic
Mass extinctions are extremely catastrophic events on Earth. Throughout Earth’s evolutionary history, numerous mass extinctions have occurred, with five major mass extinctions being particularly representative.

Climate Crisis That Accompanied The Great Dying Mass Extinction Event
The mass extinction that ended the Permian geological epoch, 252 million years ago, wiped out most animals living on Earth. Huge volcanoes erupted, releasing 100,000 billion metric tons of carbon […]

Sediments Reveal The Ancient Ocean During a Mass Extinction Event
About 183 million years ago, volcanic activity in modern South Africa unleashed an estimated 20,500 gigatons of carbon dioxide (CO2) into the ocean-atmosphere system over a period of 300 to […]
