The main theory is the asteroid theory. 65 million years ago a comet/asteroid collided with Earth which changed the climate and that resulted in to much for the Dinosaurs.

Some Scientists think that there was a severe Ice Age throughout Earths history there have been many Ice Ages which changed temperatures freezing Earths water so Dinosaurs couldn't live.

Dinosaurs became extinct by a volcano eruption some died because of a comet so that is why some dinosaurs are extinct

As dinosaurs were thought to be cold blooded, it would have been hard for them to cope with such cold conditions.

When the meteorite hit the earth it wiped out all the plants which meant the plant eaters died and the meat eaters died because they couldn't eat the plant eaters.

It is a well known fact that sometimes volcanic gas killed some of the dinosaurs.

It has also been suggested that disease killed off the dinosaurs.A very deadly contagious disease may have circulated among the dinosaurs forcing them to become extinct.

It is a known fact that it could of been climate change that killed them because water would of dried up and plants would have died so dinosaurs would of died.

Is it also a possibility that some dinosaurs evolved into birds because some fossil evidence suggests that some dinosaurs that lived developed wings and feathers.

It was also known that an asteroid hit earth on the Gulf of Mexico 65 million years ago! I think this is the most likely theory as they have found lots of information to support this.

I beleive the theory is around 65 million years ago a massive meteorite crashed into the Gulf of Mexico, throwing ash and dust into the atmosphere for years. This killed off almost all plant life and animal life on Earth at that time.

Well done everyone I'm really impressed with the amount of parent responses. Those of you who got your parent to respond can have 3tokens for each response.

Dinosaurs became extinct because asteroids came down causing distruction,fire and killing the animals!
My theory or scientists is that they got hit with a meteorite and all died. That's my theory on how Dino's became extinct.

They died because the asteroid wiped out most of them, then a volcano erupted, the ones that survived died in the ice age. That was the end of dinasours.
