So the dinosaurs got killed and did not instantaneously evolve into birds.

There isn't a soul in this thread who so much as implied that such a ridiculous thing occured.

That didn't help. Who is it that you are arguing against?

Yes, because referencing a reply that I already said was unhelpful is sensible response...

Well maybe but the likehood of the 45 percentile rejection in unknown boundary layers. ..............

Are you being hard to understand on purpose? This discussion would progress much more smoothly if you spoke plainly instead of referring me back to things that you've already said.

The answer appears to be yes.

And verging on spam.

Very constructive.

In a (probably vain) attempt to break the cycle of spam by Petrochemicals, I'll answer the title by saying, "we don't know for sure, but the asteroid impact that happened 66 million years ago probably had a big influence on it". That being said, there was recently some good evidence found for the survival of non-avian dinosaurs for about half a million years after that impact. For some reason, I'm having trouble finding the article right now, though.

This is the op.

Now the extinction at the kt boundary wiped the dinosaurs out pretty much, some survived in limited pockets apparently.

But why did they die out?

Dinosaurs where of all sizes and persuasions. If they where cold blooded why did the reptiles survive? If warm why where the mammals spared? Why would an entire clave of creatures perish and not any of the others?

This is the op.

Okay, I feel completely stupid that the very article I was referencing was right there in the first post all along...

...and so it seems that the news wasn't recent at all. That article is from 12 years ago.

[Just thinking]

Why would an entire clave of creatures perish and not any of the others?

Large animals are far more exposed a little lizard can be covered by a large rock but a dinosaur is out in the open and will be consumed by the heat and shock wave of an impact. Plus smaller creatures can be preserved by means of floating debris after such an event. Warm ground and cover are vital for the protection of the smaller animals.
