No.
But they died because of the lack of sunlight!
The suggested theory is that due to an streiod hitting the surface of earth,large plumes of dust was sent up into the atmosphere which blocked out sunlight and played havoc with the weather systems of the planet.All this cahnged the enviornment of the dinos in a big manner and they simple couldnot adapt themselves to the cahnging enviornment and died out.
so the fact that dinos died out due to lack of sunlight is incomplete in itse;f but it is one of the resons for the extinction of dinos.

The asteroid theory is favourite but many also believe the huge volcanic eruptions that happened in India at the end of the Cretaceous may also have been a contributing factor.
"The Deccan Traps formed between 60 and 68 million years ago,at the end of the Cretaceous period. The bulk of the volcanic eruption occurred at the Western Ghats (near Mumbai)some 66 million years ago. This eruption may have lasted less than 30,000 years. The gases released in the process may have played a role in the extinction of the dinosaurs"

No .... they were already exposed to sunlight.... they died becoz of the after effect of a huge meteor which hit earth & caused a massive destruction.... when it hit the earth millions of tons of rocks & debris flew as high as 100 kms in sky & covered the whole earth atomsphere... The blaze from it went so hot that any thing in radius to thousands of kilometeres was charred.,... then there was no sun light for months & acid, lava & rocks rained... the whole plant life perished & then most of the animal life including Dinosaur also....

Possibly, it would have to have been massive UV exposure due to perhaps a lack of protective greenhouse gas at the time.
Most research suggests that they died out due to a sudden climate change brought on by Meteor impact. The whole thing with a meteor impact 'kicking up dust' and suffocating everything is too radical to be true.

no, died of hunger then a big mass changed the landformtation then all the dinosaurs where underneath the ground & thats how they found them but not all of them

No. I don't think so. No one really knows for sure, but more and more scientists are leaning towards the asteroid theory.

I doubt it
I suspect the coming of humankind had something to do with their demise.
