Further confirmation of what all the evidence pointed to anyhow....

Temperatures probably cooled significantly around the globe before warming in the following centuries, wildfires on an unprecedented scale may have burned and acid rain might have poured down.

The ozone hole grew to an enormous size, and greenhouse gases such as carbon dioxide and water vapor were introduced into the atmosphere without any regulatory oversight. HIV/AIDS and other diseases of the immune system may have been rampant as well. Homelessness was widespread, as was a lack of affordable health insurance.

But, but, who was driving the SUV's back then that warmed the planet?

The one impact theory makes sense. Life had already evolved, long after the bombardment. The possibility of two earth-shaking meteors that close are pretty remote, and if it did happen it was probably a split rock.

Still very fascinating. When I was in college there were still articles suggesting volcanic activity caused the dinosaur extinction.
Makes one wonder if these impacts are on a regular period or if a random one could be coming in the near future.

[JennysCool]

The single-bullet theory?

[dfwgator]

The real reason dinosaurs went extinct.

You are pinged!

Turf battle?

I understand that there was a large flood back in the day. A flood that encompassed the entire earth … could be the reason for the extinction of so may species.

"Further confirmation of what all the evidence pointed to anyhow...."

Yup. I never paid much attention to the other arguments.

[taxesareforever]

I think the dinosaurs all died because they got tired of constantly being killed off by the scientists.

THIS IS PURE B.S. Everyone, and I mean EVERYONE KNOWS that an impact did not kill off all the TRex's. It waz THEM SUV'S!!! SUV'S I TELL YOU. SUV'S DID IT. The Dims said so.

[SmartAZ]

Dinosaurs were extincted, but frogs were not. Frogs were there, and we still have them. The impact theory does not explain why dinosaurs died and frogs didn't. It also doesn't explain why most plants before that time were gymnosperms and most plants since then are angiosperms.

ONE IMPACT ONLY

Well put. Okay, actually, I have paid attention to other arguments, but none of them held water, and were really just shrieks on the retreat. The impact denial camp has been getting a bit more publicity lately, and will be around for a while yet because they're tied in with the global warming crap, and because sudden extinction by deux ex machina (okay, used that phrase twice in a week) screws up diehard gradualists. I don't mind that they're diehards, just as long as they actually die. ;')

[Wiseghy]

Makes sense. I always thought that all the theories about complex reasons for Dino extinction ignored the basic simplicity of Occam's razor, i.e.; big meteor=dead Dino's. Why make it complicated?
