The mass extinction at the end of the Permian period, known as the Permian-Triassic extinction event, occurred around 252 million years ago. This event marked the transition from the Paleozoic Era to the Mesozoic Era, leading to the most significant loss of biodiversity in Earth's history, with approximately 90-96% of marine species and 70% of terrestrial vertebrate species going extinct. The aftermath of this extinction paved the way for the rise of the dinosaurs and other new life forms in the Triassic period.

What were some major events in the Permian time period?
During the Permian period, Earth experienced the formation of the supercontinent Pangaea, extensive glaciation in the southern hemisphere, and the diversification of reptiles. The Permian-Triassic extinction event, the largest mass extinction in Earth's history, occurred at the end of the period, resulting in the loss of around 90% of marine species and 70% of terrestrial species.
What event may have triggered the mass extinction at the end of the permian period?
The mass extinction at the end of the Permian period, known as the Permian-Triassic extinction event, is believed to have been triggered by a combination of factors, including massive volcanic eruptions in the Siberian Traps. These eruptions led to significant climate change, increased carbon dioxide levels, and ocean acidification. Additionally, changes in sea levels and anoxia in ocean waters further contributed to the collapse of ecosystems, resulting in the loss of approximately 90% of marine species and 70% of terrestrial vertebrate species.
In what era did The largest mass extinction in history wiped out approximately 90 percent of all marine animal species?
I believe in cretaceous eraThe Permian Extinction at the end of the Permian era wiped out over 90% of all life on Earth. It happened around 248 million years ago. We think it was a combination of volcanism, and massive global environmental change. There is some evidence (very little) that a comet or asteroid hurried things along.
What age of geologic time ended with the great extinction?
Well, there have been several "great extinctions" in earth's history, but the most recent one was the Cretaceous-Tertiary event, ending the Cretaceous. That was c. 65 million years ago.
The Ordovician period follows the extinction at the end of which period?
The Ordovician period follows the extinction at the end of the Cambrian period.
What era had 95 percent of species die out?
The worst known mass extinction in Earth's history was the Permian-Triassic Extinction Event at the end of the Permian period. The Permian period was the last period of the Paleozoic Era.
What is Permian?
The Permian was the last period of the Paleozoic Era, spanning 299-351 million years ago. It was a time during which reptiles diversified. It ended with the Permian-Triassic extinction event, the largest mass extinction in Earth's history.
Which eras ended with a mass extinction?
Two major eras that ended with mass extinctions are the Permian-Triassic extinction event, which marked the end of the Permian period, and the Cretaceous-Paleogene extinction event, which marked the end of the Cretaceous period. These events had profound impacts on life on Earth, leading to the loss of a significant number of species.
What is a poisonous gas that has been credited with taking part in the mass extinction that occured at the end of the permian period?
fromy research it was caused by hydrogen sulfide
What event marks the end of both the Paleozoic Era and Mesozoic Era?
The Permian-Triassic (P-Tr) Extinction Event is widely recognised as the greatest extinction event on Earth. It is also known as the "Great Dieing".It occurred 251 million years ago marking the end of the Permian Period and the start of the Triassic Period.It also marks the end of the Paleozoic Era and the start of the Mesozoic Era. Estimates have suggested that 96% of marine species and 70% percent of land vertebrate species became extinct. It is also the only known mass extinction of insect with 56% of insect families and 83% of insect genera becoming extinct.Little is known of the cause of the mass extinction but theories range from meteorite impacts, to volcanism, to sea level fluctuations.
The largest extinction the world has ever known occurred at the end of which period?
The largest extinction event known is the Permian-Triassic Extinction Event, 250 million years ago. It is nicknamed "The Great Dying" in reference to how 96% of all known marine animals and 70% of all known terrestrial vertebrates at the time went extinct due to climatic changes because of volcanic eruptions and the formation of Pangaea.
What were some major events in the Permian time period?
During the Permian period, Earth experienced the formation of the supercontinent Pangaea, extensive glaciation in the southern hemisphere, and the diversification of reptiles. The Permian-Triassic extinction event, the largest mass extinction in Earth's history, occurred at the end of the period, resulting in the loss of around 90% of marine species and 70% of terrestrial species.
Why did trilobites become extinct?
The trilobites went extinct during the mass extinction at the end of the Permian period.
What is a period of earths history that lasted 245 to 208 million years ago?
The period of Earth's history that lasted 245 to 208 million years ago is the Triassic period. This period followed the Permian period and preceded the Jurassic period. It was a time of recovery and diversification of life after the mass extinction at the end of the Permian period.
What event may have triggered the mass extinction at the end of the permian period?
The mass extinction at the end of the Permian period, known as the Permian-Triassic extinction event, is believed to have been triggered by a combination of factors, including massive volcanic eruptions in the Siberian Traps. These eruptions led to significant climate change, increased carbon dioxide levels, and ocean acidification. Additionally, changes in sea levels and anoxia in ocean waters further contributed to the collapse of ecosystems, resulting in the loss of approximately 90% of marine species and 70% of terrestrial vertebrate species.
What were the 5 major extinction events in earth history?
They are the end-Ordovician extinction, end-Devonian extinction, end-Permian extinction, the Triassic extinction, end-Cretaceous extinction.
Which two eras ended with mass extinction?
The Permian-Triassic extinction event, around 252 million years ago, marked the end of the Permian period and the beginning of the Triassic period. It is the most severe extinction event in Earth's history, wiping out approximately 95% of marine species and 70% of terrestrial vertebrate species. The Cretaceous-Paleogene extinction event, about 66 million years ago, ended the Cretaceous period and led to the extinction of the non-avian dinosaurs and about 75% of all plant and animal species.
