George Bush is history's greatest killer. Don't you listen to the liberal babble on the nightly news....

It's not because the liberals aren't trying...

Bush knew about the impending K-T extinction and didn't warn the dinosaurs.

The geologic record shows that cataclysmic volcanic eruptions occurred around the same time as two periods of mass extinctions.

There is also evidence that the two may be linked. The Shiva crater is contemporaneous with the Chicxulub in the Yucatan and some geologists link it to the Deccan flood basalts. The Siberian flood basalts are contemporaneous with the P-T boundary, and are large enough to have covered a large impact crater.

Cousin Eddie would know.

Ever shoot a watermelon with a high-power rifle?

Think of "hydrostatic shock" on a planetary scale.

Ever shoot a watermelon with a high-power rifle?

Just another Saturday afternoon, sittin' on the front porch with not a lot to do...

[sphinx]

Yeah, maybe, but a big blow at Yellowstone would still be pretty bad news.

Under the Homeland Security Act of 65 million BC, he also arrested any of the dinosaurs who were caught talking about it!

I made the mistake of shooting the watermelon with a .45 at 5 yards.

Some of the chunks will fly 10 yards unless they hit an intervening object, like a guy dumb enough to stand only 5 yards away (c8

And the K-T extinction hit the women and minority dinosaurs hardest.

Are you kidding, Shrubbie plotted the extinction of the dinosaurs. Why do you think he isn't releasing any info to the Senate committees who are only interested in obtaining the truth and have no partisan desires. If we could only elect Dean, he could save the dinosaurs. I hear he has a plan.....

and to think Liberals use to make fun of conservatives for Black Helicopters and shooting watermelons. Those buffoons are convinced Bush had Welstone killed, plotted a war for Haliburton could profit, and let terrorist fly planes into the trade centers so could get re-elected. The kookery on the left is becoming their 'mainstream'.

Meanwhile, France ponders how to surrender...

Nah, this sounds like the work of a SUV to me.

Think of "hydrostatic shock" on a planetary scale.

I would be more inclinded to look at the lunar model, where large impacts from billions of years ago filled up with lava. A large impact could cause an eruption. In the case of the Shiva crater, it landed right off the west coast of India, where the Deccan traps are located. And the Siberian traps are large enough to have covered a major impact crater, and it would be very difficult to locate an impact structure under it.

[Poohbah]

Are you kidding, Shrubbie plotted the extinction of the dinosaurs.

Actually, it was plotted by his handlers and his fellow members of Skull & Bones. Shrubbie's too dumb to think up anything like this, remember?

[Poohbah]

But there are also signs of other volcanic eruptions--massive ones--thousands of kilometers away. So Earth bleeds out of the entry wound, and there's an exit wound, and everyone insists that there was a second mass driver on the Grassy Knoll of Nix Olympica (c8

So, smart guy, you're trying to tell me that Arlen Specter is a geologist?
