The mass extinction, known as the Permian extinction, affected both plants and animals on land and in the seas. Scientists do not know what catastrophic events caused the mass extinction, many kinds of organisms suddenly became extinct, as much as 90% of Marine species may have died out.

Which eras ended with a mass extinction?
Mesozoic and Paleozoic
Why did many planets die at the end of the mesozoic?
Scientists believe the Cretaceous-Paleogene extinction event, or the plants dying at the end of the Mesozoic Era, was caused by a massive asteroid/comet impact. The theory suggests that the impact had catastrophic effects on the environment, including an impact winter, which prevented the plants from carrying out photosynthesis.
What event ended the paleozoic and mesozoic era?
Extinction did.
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.
What percent of earths species died off at the end of the paleozoic era?
Statistical analysis of the fossil record indicates somewhere around 35% of all species disappeared at the end of the cretaceous. (There is considerable margin for error in that figure--we don't have a good estimate for the number of species that exist today, even). http://en.wikipedia.org/wiki/Cretaceous%E2%80%93Tertiary_extinction_event
What does the end of the paleozoic and the mesozoic have in common?
Mass extinction
The ends of the geologic eras such as the Paleozoic and Mesozoic are marked by?
mass extinction
What event do scientist think may have caused the mass extinction at the end of the Paleozoic?
the climate change during the shifting of the plates that was causing the making of Pangea
Which eras ended with a mass extinction?
Mesozoic and Paleozoic
What event happened at the end of the Paleozoic era?
A large mass extinction took place at the end
The Paleozoic Era is noted for what two changes?
The explosion of life in the Cambrian and the mass extinction of the Permian.
Why did many planets die at the end of the mesozoic?
Scientists believe the Cretaceous-Paleogene extinction event, or the plants dying at the end of the Mesozoic Era, was caused by a massive asteroid/comet impact. The theory suggests that the impact had catastrophic effects on the environment, including an impact winter, which prevented the plants from carrying out photosynthesis.
When was mass extinction of 99 percent of all life?
The Permian mass extinction wiped out the highest percentage of all life forms, though I thought it was closer to 96%. It occurred 251 million years ago, between the Paleozoic and Mesozoic eras, and was caused by an extreme volcanic eruption in what is now Siberia.
What caused each mass extinction?
Asteroids.
What may have caused the first mass extinction 65 million years ago?
An asteroid impact caused a mass extinction about 65 million years ago
What event ended the paleozoic and mesozoic era?
Extinction did.
Relationship between extinct and mass extinction?
Mass extinction is when many animals go extinct within a short period of time caused by the same variables/factors leading to the mass extinction.
