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.
The mass extinction of dinosaurs occurred around 66 million years ago during the Cretaceous-Paleogene (K-Pg) boundary.
Several periods of mass extinction
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.
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.
It is not a "who" but a what that killed off the dinosaurs. It is thought that an asteroid hit the earth causing a prolonged winter which killed off all the plants so they starved to death and died.
The formation of the ozone layer
Pterodactyls died out along with the dinosaurs and many other animal and plant species during the K-T extinction event. It is believed that an asteroid, along with other environmental changes, struck the Earth and contributed to the mass extinction. Dinosaurs, pterosaurs, and many marine reptiles were not able to cope, so they went extinct.
