Were dinosaurs done in by gas?

When a giant asteroid slammed into the Yucatan Peninsula 65 million years ago, the results were devastating: rock and ocean water vaporized, searing debris flung into outer space, and a smoldering hole in the Earth almost 75 miles wide.

Scientists debate whether the cataclysm was enough to wipe out the dinosaurs. But a new set of experiments shows the impact produced a huge amount of carbon monoxide, a compound commonly found in car exhaust. The sudden pulse of gas may have been enough to cause a large spike in global temperatures, and trigger a mass extinction.

No, water(massive Global Flood)!

Global warming screed. :’) Still interesting, in that asphyxiating gas rolling across the face of the world could have accomplished a lot of the mass extinction event.

No, I'm afraid of assteroids. ;-)

I'm a little suspicious also because of the obvious global warming from greenhouse gas angle. Maybe it's because I'm not a scientist, but why is it so hard for some people to accept that an impact capable of creating a massive crater the size of the Yucatan crater would have cataclysmic effects, especially on megafauna???

Several years ago over here, a young couple were hiking in the national park and strayed off the marked trail, exploring on their own, it's supposed but no one knows. They were found dead in an area of high sulfur dioxide concentration from cardiac edema a few hours after reported missing.

Yeah, this can happen locally but to the scale of a mass extinction is shaky. Pneumonia (bacterial or viral) from stress resulting from the vog is the more likely culprit impacting herd animals which in turn put the predators out of business in turn.

After that Vermin Ruled the Earth.

We still do...

[Rocky]

Nah, I think it was Bronto Flu that got them.

[MIchaelTArchangel]

They must have been eating in Boston to get that much gas that they all died.

Some of us are evolving.....the rest reside in Foggy Bottom.

To mix my metaphors, that’s sort of a sane voice howling in the wilderness of the pseudo-science/news-media complex.

thanks, bfl

Back in the 1980’s I read a book called “The Dinosaur Heresies” by Dr. Robert Bakker. In the final chapter Bakker pointed out that the mass extinctions did not occur over night, but over a period of several million years. I presume this is confirmed in the geologic record; that fossils of the extinct species were spread over a several million year period in and around the time of the meteorite impact. Bakker then offered his theory on what induced the mass extinctions; it had nothing to do with the meteor impact.

This article again shows the insidious nature of the ‘warmists’. What really killed all the dinosaurs according to them was not the meteorite impact but the global warming that resulted from it. So, the real culprit is global warming, no matter what the source, whether giant meteors or SUV’s. Another instance of junk “science” at its ‘best’.

A few recent threads were about the extinction taking some 300,000 years. Same idea.

Also, the entire surface would be under cloud cover, in Gene Shoemaker’s words, “in the time on the order of an hour and a half” and the cloud cover would block sunlight from reaching the surface, probably for weeks at least. And of course, that would be followed by really ugly precipitation, including acid rain.

[Redcitizen]

Yes it was Boston Baked Beans that did the trick.

Dinosaurs were notorious for drinking beer and eating chili.

Let's try refining the expostulation:

It is time for some scientists* to stop putting forward unprovable conjectures disguised as hypotheses.

Better?

*The same some scientists the press is fond of quoting, but never identifying.

No. Why should they shut up to satisfy you? Discovery, like this thread, is for people interested in the speculation and debate.
