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.
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.
How did the mesozoic era end?
Mammals, primates and most sea animals were extinct during the mesozoic era. And what caused this is a comet hit earth and the lack of sunlight that was able to reach earth the plants died out and without a food source so did the dinosaurs
Were there dinosaurs in the Paleozoic Era?
No, dinosaurs did not appear until the Mesozoic Era, which followed the Paleozoic Era. Dinosaurs first appeared around 230 million years ago at the start of the Triassic period. The Paleozoic Era ended around 252 million years ago.
What era began and ended with mass extinctions?
Paleozoic - climate change Mesozoic - meteor
When the mesozoic era ended?
It ended about 65 million years ago
What began and ended with mass extinction?
Mesozoic
What era ended with a massive impact?
The Mesozoic era ended with a massive impact caused by an asteroid hitting Earth, leading to the extinction of the dinosaurs.
When did Mesozoic era begin and end?
The Mesozoic era began roughly 250 million years ago, and ended 65 million years ago. (This Era ended because of the K.T. extinction)
Where is the crater that is evidence of the meteorite impact that ended the Mesozoic?
The Chicxulub impact crater in the Gulf of Mexico is the most likely suspect for the meteorite impact that caused the Mesozoic extinction. The crater is 180 km in diameter, suggesting that the impacting body was approximately 10 km in diameter.
What era ended in the largest mass extinction in earth's history?

What dinosaurs were from the palezoic era?
None. Dinosaurs first appeared in the Mesozoic Era, after the Paleozoic ended.
What are two ways the climate has change since the Mesozoic?
During the Cretaceous, flowering plants and deciduous trees came into their own. After the Mesozoic ended, grasses, which may have existed as far back as the Jurassic, but in very subordinant roles, began to dominate the unforested areas.
What event marked the end of the Mesozoic Ara and the beginning of the Cenozoic?
An asteroid impact
