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.
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.)
Birds are direct descendants of dinosaurs so they did not die out.
Dinosaurs Don't Die was created in 1975.
Some of the major topics paleontologists discuss include: How did dinosaurs die out? Were dinosaurs warm blooded? Which theropods had feathers and which ones only had scales? How active were dinosaurs? How fast could they run?
Yes
they saw you
They already did. All the dinosaurs died out 65 million years ago.
most dinosaurs died of the meteor but a couple of periods before the cretacious period there was the permian period in which 95% of all life died as all the volcanoes erupted and shot up gas (methane) and killed them. a crocodile/ aligator is a dinosaur, 1 of the remaining dinosaurs alive as all did not die.
Dinosaurs never flew dinosaurs were land reptiles although some dinosaurs could swim
No
some dies, some survived, there were billions of dinosaurs
