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.

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.
What plants would you see in the mesozoic era?
After the great Permian extinction 248 million years ago, at the end of the Paleozoic Era, plants began to evolve rapidly. Some of these have actually survived into modern times with very little change. Many others were overwhelmed with the appearance of flowering plants at the end of the Mesozoic.Four groups of plants dominated Triassic and Jurassic landscapes:Ferns were the dominant understory plants, with a variety of foliage types.Ferns, Tree ferns, Cycads and cycadoides created the middle story of foliage.The over story of the Triassic forest was formed by a variety of conifers that are most closely related to the modern genera Araucaria (The genus that includes the Norfolk Island Pine)Possibly one of the earliest flowering plants from the Mesozoic Era that still exists today is the Ginkgo.
How does the end of the Cenozoic era compare to the climate near the end of the Mesozoic era?
it is cooler {apex}

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.
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.
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.
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.
Dinosaurs went extinct at the end of what era?
Mesozoic era
Do humans evolved in the Eocene period?
No. The dinosaurs rose in the Mesozoic era. The end of the Mesozoic era was also the end of the dinosaurs. The era following is the Cenozoic, which we are still in today.
