what do you think the real reason is that dinosaurs got extincted?

Answer 1

The dinosaurs were reptiles. Reptiles are cold blooded. They cannot survive in cold weather for long periods of time. When the great ice age came, the earth was cold, to cold for the dinosaurs to live, plus most of the available food was gone. The combo of this plus competition for mates and other needs put the end to the dinosaurs. This is what excepted by most scientist.

Answer 2

It's not entirely clear; there is some speculation that dinosaurs were decreasing in numbers towards the end of the Jurassic period, but that may not be true. It is generally accepted that the extinction of the dinosaurs coincides approximately with a massive meteorite impact, and that the effects of the impact would have made life difficult for dinosaurs. Unfortunately, no-one was there to take notes, so no-one knows whether that was the primary cause of dinosaur extinction or whether it was some combination of disease, stress, cosmic radiation, "nuclear winter" (ie meteorite-effect cooling and shading of the earth leading to disruption of food webs, etc.), global climate changes, sunspots, alien hunting parties, cigarette smoking, or perhaps other factors we don't know about. All we know for sure is that there was a mass extinction event at that time that included the dinosaurs and many other animals. Some things (including birds and mammals) got through it OK and continue to show up as fossils into the next geologic periods; these are the things that then diversified greatly and became the most common land animals, filling the roles that the dinosaurs had filled before.
Personally, I lean toward the meteorite/nuclear winter hypothesis, but I realize that the information available to support this is very scanty.

Answer 3

I believe it had to do with interdependence. There was a dramatic temperature change, which caused a lot of plants to die.

that made it harder for herbivores to find food, so many began to die.

with no herbivores to feed off of, the carnivores had to start feeding on other carnivores, until all the dinosaurs were gone.

they themselves ate out the entire race of dinosaurs, because of the loo of plants.



now i know that no scientists have ever though about this happening, and most believe in the whole meteor shower, but i think this is what really happened.

Answer 4

I have researched information about dinosaurs, to my scientific conclusion, the dinosaurs are colded-blooded reptiles, and reptiles depends on heat to warm their blood. How can a cold-blooded species servive in a cold climate?
I do believe that El-Nino/El-Nina existed during the dinosaur time. The earth was going through some difficult transformation and some animals couldn't adapt to the change of weather and other changes of servival needs. This is my conclusion about the change of the dinosaurs history.

Answer 5

there's a layer of rock in the earth's crust that has an anomalously severe concentration of iridium, this sediment is worldwide and is not cutting-edge in such concentrations someplace else in the rock column. Iridium is adequate in asteroids and this, alongside with the effect crater close to city of Chicxulub, Mexico particularly lots confirms that an effect, accompanied via a lengthy era of darkness and worldwide cooling killed the dinosaurs.

Answer 6

Well scientist think that a meteor hit the earth and blow up a great amount of dust so great that it covered all of earth's atmosphere.

I think that either a flood, Ice Age, or a famine came, first to the leaf-eaters causing them to die, and then the meat-eaters to die off.

Answer 7

Meteor strike the size of the gulf of Mexico and the resulting ice age

Answer 8

They aren't extinct. They're just hiding.

Answer 9

they never existed in the first place.

Answer 10

great flood.
