Explanation:

The most devastating mass extinction in Earth's history was the Permian extinction, which occurred at the end of the Permian period. It resulted in the loss of around 95% of existing species at that time. Warming of the Earth's climate due to volcanic activity in Siberia is believed to have been a major factor in this extinction event.

Dinosaurs went extinct at the end of the Cretaceous period due to an event caused by a meteorite. The impact threw dust into the atmosphere, blocking sunlight and leading to a chain of events that ultimately resulted in the extinction of dinosaurs.

Dinosaurs went extinct approximately 65 million years ago, at the end of the Cretaceous period, due to the impact of a massive asteroid near the Yucatan Peninsula in Mexico.
