In the Late Cretaceous (65 million years ago).
When the meteorite hit Earth and killed the dinosaurs.
The dinosaurs fell victim to a mass extinction.
We are still not sure what caused the mass extinction of the dinosaurs, though an asteroid impact seems to be the popular theory.Scientists believe we may be heading towards another mass extinction event.
65 million years ago
Several periods of mass extinction
The Cretaceous period ended with the extinction of the dinosaurs. The period that followed the mass extinction was called the Paleocene. This was a time of the mammals.
I think so.
An asteroid from space, like the one that killed the dinosaurs, which was a mile in width.
No. The Jurassic was in the middle of the dinosaurs' reign on Earth. The time period after the extinction of the dinosaurs is referred to as the Paleogene or the Tertiary.
Mass extinction. A mass extinction typically occurs after a catastrophic global event. This event could be a bolide impact (such as the impact 65 million years ago that killed the dinosaurs, the most famous example of a mass extinction), increased volcanism, climate change, or something similar.
The formation of the ozone layer
The mass extinction of dinosaurs were caused volcanoes that cause global warming with their toxic gases, therefore, killing the plants, starving the plant eating dinosaurs to death, and with no more plant eating dinosaurs, the meat eating dinosaurs died, too.
