The Permian-Triassic Extinction Event happened at the end of the Paleozoic Era. It is widely recognised as the greatest extinction in Earths history. It was also known as the "Great Dying". 90% of all marine species, 60% of all land vertebrates and 58% of all genera of insects became extinct. It is the only known mass extinction of insects.
Warm, shallow seas covered most of Earth's surface near the end of the Paleozoic Era.
The event that marks the division of the Paleozoic and Mesozoic era is the breaking up of the Pangaea
The Permian extinction event.
The permian period was the end of the paleozoic era.
That would be 251 million years ago. The end of the Paleozoic era marks the beginning of the Mesozoic. The last period of the Paleozoic era was the Permian, and the first period of the Mesozoic era was the Triassic; hence the extinction event (the biggest extinction event in the earth's history), the Permian-Triassic extinction, which defines the border between the eras.
The permian period was the end of the paleozoic era.
