What do YOU think killed the dinosaurs?

Question

I don't know...I'v heard different opinions about how dinosaurs died, but I'd like to hear more. :)

All I have so far is : The flood of Noah killed them, or the meteors. ( Sorry I forget how to spell meteors... o_o' )

Answer 1

It was the meteor. Just one which left a nice big crater. There is plenty of evidence for this and there is more all the time if you read the scientific papers. Other people think that climate change managed to kill them off many thousands of years before the meteor struck. No serious scientist thinks that Noah's flood did it.

Answer 2

There have been several mass extinctions in the history of the Earth, not just the dinosaurs.  These extinctions may have been caused in many different ways.  Some have to do with changes in sea level, or with global warming or global cooling, and other reasons.  As for the event 65 million years ago that killed the dinosaurs, I tend to agree with the current theory that it was an asteroid.  But for a better understanding and overview of mass extinctions and their causes, you might want to read this wikipedia page -- http://en.wikipedia.org/wiki/Mass_extinc...

Answer 3

Heres my opinion, I truly think that the cloud of dust from the impact of an asteroid that hit Earth did cease life that time.  I mean if that happened today, I believe the same effects would occur and we would all die if we didn't already die from the impact itself, we would eventually die from the blockage of sunlight.

Answer 4

I think it was a combination of two factors. Firstly the impact in the Yucatan which, as people have already pointed out, is well documented by the Iridium spike in the sedimentary record.

I also think that the emplacement of the Deccan traps would have had a major contribution. It was essentially a massive flood basalt eruption which would have released enormous amounts of volcanic gases. This in turn would have driven a change in global climate. Bear in mind that the fossil record shows more than a halving of the number of species of ammonite from 3 million years to 1 million years before the asteroid impact, a trend which is repeated in other fossil records as well.

I don't think there's much doubt that the Yucatan impact finished off the dinosaurs, but I think they were probably well on the way to extinction by that point.

Answer 5

Santa Claus DUH!

=D

thumbs up if u agree

Answer 6

65 million years ago a astroid fell in the gulf of mexico . that would had covered the earth.  it had blocked down the sun for a long time . so the plants died , and finaly meat eaters starved . another reason was ,the climate was changing and much part of the water was becoming in land  . and many

volcanoes were erupting .but when all the dinosaurs died their un hatched egg were eaten by  mammals. but along with the dinosaurs marine reptiles and flying reptiles also died .

but some people also say their brain were to small .but this is not treu because dinosaurs lived for 150 million years 76 times more than humans.

Answer 7

Dinosaurs went extinct 3 or 4 thousand years ago because of the after effects of the Flood in Noah's day.

This has been confirmed. Scientists have already figured it out.

Answer 8

Huge asteroid that hit the earth 65 million years ago.  it left a huge crater under the ocean on the yucatan peninsula and a layer of iridium all over with world at the precise point of the K/T boundary, 65 million years ago.  iridium is a rare metal on earth, but plentiful in asteroids.
