Some believe it was a natural occurring ice age.
Others say it resulted from the impact of an asteroid, comet, or meteor that released enough debris into the atmosphere to trigger a "impact winter" that blocked sunlight from reaching the ground and prevented plants needing photosynthesis from growing resulting in the starvation of dinosaurs and other creatures.
It could also have been the great flood that has been recorded all over the world and the dinosaurs never made it into Noahs ark :)
The dinosaurs fell victim to a 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.
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.
When the meteorite hit Earth and killed the dinosaurs.
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.
Jurassic period
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.
There was a mass extinction, killing of the dinosaurs before early hominids (humans) came along.
Notable extinctions during the last mass extinction included all non-avian dinosaurs, pterosaurs, plesiosaurs, and ammonites.
Dinosaurs
The modern era that began approximately 65 million years ago with the mass extinction of the dinosaurs is called the Cenozoic Era.
