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.

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.


What happened at the end of the Mesozoic era but did not happen at the end of the Paleozoic era?

There were major asteroid impacts.


What era and period occurred in 251 to 65 million years ago?

An era is a span of time, so there was no era at that time. It was, however, the end of one era and the beginning of another. More specifically it was the end of the Mesozoic and the beginning of the Cenozoic.


What is The Oldest Period in the Mesozoic Era?

The oldest period in the Mesozoic Era is the Triassic period, lasting from about 251 to 201 million years ago. It followed the Permian mass extinction and saw the early diversification of dinosaurs, as well as the first appearance of mammals and birds.


What birds lived in the mesozoic era?

There is currently no evidence of grass in the Triassic Period. Until recently it was thought that grass evolved around 55 million years ago but recent findings suggesting that grass became common 66-65 million years ago comes from the very end of the Cretaceous Period. Some dinosaur coprolites show material that appears to have been grass. It is now believed that Grass's evolved sometime in the late Cretaceous and became widespread just prior to the K-T Extinction Event.
