The permian extinction happened about 251 million years ago right after the carboniferous period. Many scientists suspect a comet or asteroid impact, although direct evidence has not been found. Others believe the cause was flood volcanism from the Siberian Traps and related loss of oxygen in the seas. Still others believe the impact triggered the volcanism and also may have done so during the Cretaceous-Tertiary extinction. The Permian-Triassic catastrophe was Earth's worst mass extinction, killing 95 percent of all species, 53 percent of marine families, 84 percent of marine genera and an estimated 70 percent of land species such as plants, insects and vertebrate animals.
The Permian Period started at from 280 to 248 million years ago.
The Permian Period was the last period of the Paleozoic Era. It lased from 299 to 251 million years ago.
The Permian Period is the final period of the Paleozoic Era. It began about 290 million years ago and lasted until 248 million years ago.
The Permian Period started about 299 million years ago at the end of the Carboniferous and ended at the start of the Triassic 251 million years ago.

Was there an ozone layer in the permian period?
During the Permian period, which lasted from about 299 to 251 million years ago, there was an ozone layer forming in Earth's stratosphere. This layer started to develop during the Proterozoic eon, approximately 500 million years ago, and continued to evolve through the Paleozoic era, which includes the Permian period.
Which was NOT a subdivision of the Mesozoic era?
The Cenozoic era was not a subdivision of the Mesozoic era. The Mesozoic era is subdivided into the Triassic, Jurassic, and Cretaceous periods.
When did the present geologic era begin?
Quaternary and it started 16 million years ago
In what era did The largest mass extinction in history wiped out approximately 90 percent of all marine animal species?
The largest mass extinction in history, known as the Permian-Triassic extinction event, occurred approximately 252 million years ago during the end of the Permian period. It wiped out approximately 90% of all marine animal species and is often referred to as the "Great Dying."
What are 3 plants from the Permian era?
Glossopteris: A large seed fern that dominated the flora of the Permian period, found in Gondwana. Cordaites: Tall, tree-like plants with needle-like leaves that were common in the late Paleozoic era, including the Permian. Sigillaria: An extinct tree-like plant with segmented trunks and scale-like leaves, characteristic of the Carboniferous and Permian periods.
What is the time span of the permian?
The Permian Period lasted from about 299 to 251 million years ago during the Paleozoic Era. It was the last period of the Paleozoic Era before the start of the Mesozoic Era.
How long ago did our era begin?
65 million years
When did the permian period occur?
The Permian period lasted from 290 to 248 million years ago and was the last period of the Paleozoic Era.
How long ago did the 'paleozoic' era begin?
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.
How long ago did our current era begin?
65 million years
What era did swamps form and coal begin to develop?
I believe it was during the Permian and Pennsylvanian eras.
The end of the Permian period was also the end of what Era?
The end of the Permian period marked the end of the Paleozoic Era and the beginning of the Mesozoic Era.
What Era does the Permian period belong to?
Ther Permian was the last period of the Paleozoic era.
What era was also the end of The end of the Permian?
The permian period was the end of the paleozoic era.
The final Paleozoic period?
The Paleozoic Era has seven Periods beginning with the Cambrian Period. The last period was the Permian Period which was from 290 Million to 248 million years ago.
Which era of geological time lasted the longest?
The Paleozoic Era lasted from about 540 million years ago to about 280 million years ago. It included the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian Periods.
How long ago was the era?
a long time ago :]
