There were a lot of different kinds of dinosaurs that died off at various times. However, pretty much the final curtain was something called the K-T Event, which marked the end of the Mesozoic Era and the beginning of the Cenozoic Era. It's thought that a large meteorite (perhaps 10-40 km diameter) struck the Earth, resulting in climate changes which most dinosaurs were unable to adapt to.
The K-T Event happened roughly 65 million years ago.
Dinosaurs got extinct in the cretacious era 66 millions ago. It is unknown how, but predictions are:
Meteor
Asteroid
Mosquitos
kind of... some say th kiler whale is a dinosaur and some say a meteor killed them
if temperature drops quick enough, plants die. if plants die, the dinosaurs that eat plants die. if those dinosaurs die, then the carnivorous meat-eating dinosaurs die. then, all dinosaurs die.
No
They already did. All the dinosaurs died out 65 million years ago.
AnswerYes, all the true dinosaurs died out approximately 64 million years ago. The nearest living relatives of dinosaurs are the birds.
Planet Earth, all over it.
It is believed that they did die of a meteor but no one is really positive. If they did die of a meteor than the rest probably died from all the dust in the air after the crash. Some aquatic dinosaurs did survive though that is why their are crocodiles,komodo dragons,turtles,etc...(which evolved from these dinosaurs.)
Dinosaurs Don't Die was created in 1975.
Birds are direct descendants of dinosaurs so they did not die out.
No, not all at once. Throughout the 150 million year "reign" of the dinosaurs, all kinds of groups of dinosaurs have flourished then died out. Dinosaurs living in the Triassic Period were not the same as dinosaurs living in the Cretaceous period. However, the final blow to the dinosaurs that caused them all to die out was the K-T mass extinction that occurred 65 million years ago.
During the age of the dinosaurs, various species of dinosaurs died off and new ones came along but all non avian dinosaurs died 65.5 million years ago.
A meteorite had hit the earth and there was a big explosion. And all the dinosaurs died.. :(
Dinosaurs did not die out because of plants. They died out because of a lack of plants after an asteroid impact blocked out sunlight for months or years. With all the plants dead, the dinosaurs starved.
