Which time period ended with the worlds largest mass extinction?

Correct Answer
Permian
permian

Explanation
The Permian period ended with the world's largest mass extinction. This extinction event, known as the Permian-Triassic extinction event, occurred approximately 252 million years ago and resulted in the loss of about 96% of marine species and 70% of terrestrial species. It is considered the most severe mass extinction event in Earth's history, wiping out a significant portion of life on the planet. The Permian period is therefore associated with this catastrophic event, making it the correct answer.
