Based on the popular theory that the dinosaurs went extinct due to the impact of a large asteroid, scientists think that the asteroid caused large amounts of debris to fly into the atmosphere, blocking out the sun. This caused global temperatures to drop, thus freezing the plants. In addition, without the sun the plants could not carry on photosynthesis, which caused them to die.

Why did many plants die at the end of the Mesozoic Era?
Based on the popular theory that the dinosaurs went extinct due to the impact of a large asteroid, scientists think that the asteroid caused large amounts of debris to fly into the atmosphere, blocking out the sun. This caused global temperatures to drop, thus freezing the plants. In addition, without the sun the plants could not carry on photosynthesis, which caused them to die.
Why the plant life died at the end of Mesozoic era?
No major plant groups died out at the end of the Mesozoic. However, most of the individual plants died because dust that was launched into the atmosphere by the asteroid impact blocked out the sun. However, once the dust settled after a few months. dormant seeds took hold.
When the chicxulub crater formed?
End of the Mesozoic era
What happened at the end of the mesozoic era but not at the end of the Paleozoic era?
There were major asteroid impacts.
Do dinasours exsits?
No but they did in the beginning of the Cenozoic era and the end of the Mesozoic

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 time era did the dinosaurs die out?
The dinosaurs died out 65.5 million years ago. That was the end of the Mesozoic era.
And the end f what era did all the dinosaures die?
The dinosaurs evolved at the beginning of the Mesozoic. All non avian dinosaurs died out 65.5. million years ago at the end of the Mesozoic. However, birds, which are a group of dinosaurs, are still alive and well.

When did the Chicxulub crater form?
End of the Mesozoic era
What does the end of the paleozoic and the mesozoic have in common?
Mass extinction
When the chicxulub crater formed?
End of the Mesozoic era
What dinosaurs lived in Mesozoic era?
The first dinosaurs evolved in the Mesozoic. At the end of the Mesozoic, all non avian dinosaurs became extinct. Therefor, all non avian dinosaurs, and some avian dinosaurs (birds), lived in the Mesozoic.
What happened at the end of the mesozoic era but not at the end of the Paleozoic era?
There were major asteroid impacts.

End of the Mesozoic era
Dinosaurs went extinct at the end of what era?
Mesozoic era
