Ice Age

well the so called meteor/asteroid hit earth, wiped out about 1/5 of all of the dinosaurs...then the dust in the air and volcanic activity from the collision causes more dust to fly in the air, blocking out the sunlight and dramatically reducing the temperature on the planet, almost turned into an ice age. Without the sunlight plants die, and as a result of plants dying, herbivore dinosaurs which eat a huge amount of plants a day die of hunger, and the carnivores that depend on the herbivores die of hunger as well since the herbivores are dying off. And soon the food chain breaks down and the dinosaurs go extinct

1. Near the end of the Cretaceous era, biodiversity among dinosaurs had declined. We don't know why.
2. At the end of the Cretaceous, there was a mass extinction event (caused by the Chicxulub meteor) that wiped out a lot of species. Apparently this included the remaining dinosaurs.

One of my paleontology professors doesn't think well of the meteor theory. He says that there were still dinosaurs around a few million years after the meteor hit. If I remember right, he thinks the meteor was a start, but vulcanic activity eventually lead to the end of the dinosaurs era. I dunno if it's true.

ABSOLUTELY NO ONE KNOWS 4 SURE!!! but there r a few reasonable theorys 1)kind of like global warming, a wave of warmth came. this is the 1 i believe bcuz every 15million years, the earth goes into an ice age or leaves an ice age. coming from an ice age woulda been alright but goin into 1??? dinos r not penguins, ok? as far as they ate eachother....thats funny, no sarcasm intended, though. heres a q. if they ate eachother, who or what ate the last dino?

A meteor hit near the Yucatan Peninsula in Mexico 65 million years ago causing the K-T (Cretaceous - Tertiary) or K-Pg (Cretaceous - Paleogene) mass extinction.
Extinction wasn't immediate - the meteor caused a lot of environmental effects that had huge ecological impacts over many years.

Dinosaurs died of a flood. If they didn't then explain why their bodies were fossilized. Ash won't cut it because you need some type of mud to fossilize something not dry dirt. If dinosaurs lived, then we would be dead. So, you can have to choice of have dinosaurs live or yourself.

They may exist as birds today. But as the previous answerer said, the most accepted theory at present is the meteor one.

No one knows for sure but i believe that it was from the flood in the time of Noah. A flood is one of the most excepted theories along with the meteorite theory
