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.
When did the triassic period take place?
The Triassic was from about 225 million to 190 million years ago. It is the first period of the Mesozoic ("middle life") Era.The Triassic Period is most commonly believed to have begun 251 million years ago and lasted until 199.6 million years ago.

Mesozoic era what events happend to begin and end this era?
The Mesozoic period began about 250 million years ago when the Permian-Triassic extinction occurred, probably by a combination of gradual atmosphere change and some external event like an Earth impact. The period ended about 66 million years ago with another great extinction, this one probably a combination of an impact and volcanic activity.
Which of these was NOT a period of the Cenozoic Era Tertiary Quaternary Cretaceous all of these are periods of the Cenozoic Era?
The question is very muddled but it can be answeredThe Cenozoic Era started with the end of the dinosaurs and is ongoing 65.5 mya to the present thereforeOf the above the following are in the Cenozoic:QuaternaryTertiaryAnd the following are out of (older than) the Cenozoic:Cretaceous
What era was also the end of The end of the Permian?
The permian period was the end of the paleozoic era.
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.
Details about the permian period?
In the permian period,The slow gradual collision of continental plates caused mountain building. Near the end of the Permian Period, all continental plates came together to form the single landmass PANGEA. Mass extinctions of many land and sea animals ocurred to signal the end of the Paleazoid Era.
What happened at the end of the Era?
The Permian extinction event.
When did the permian period end?
251 million years ago
When did the great extinction occur?
End of the Paleozoic era no, end of the Permian period. the cause was the great dying.
What period in which the last ammonites became extinct?
Ammonites went extinct at the end of the Cretaceous Period.

When was The largest mass extinction of the Paleozoic Era?
The Paleozoic Era spans six geologic time periods. The first was Cambrian and is the name given to a period of time in Earth's history, which spanned 570-510 million years ago. The Permian Period, which was the last period covers the time roughly 286 million years ago.
What time period was eurypterids introduced?
At the end of the Permian Period which was about 251 million years ago
What signaled the end of the Paleozoic Era?
The Permian- Triassic extinction event was the greatest extinction on Earth. 95% of all organisms died during this time period, signaling the beginning of the Triassic.
When did the triassic period take place?
The Triassic was from about 225 million to 190 million years ago. It is the first period of the Mesozoic ("middle life") Era.The Triassic Period is most commonly believed to have begun 251 million years ago and lasted until 199.6 million years ago.
