WASHINGTON (Reuters) - A single, gigantic asteroid slammed into Earth 65 million years ago, dooming the dinosaurs and many other species, scientists said on Thursday in a new study rebutting theories that multiple impacts did the deed.

An examination of rock sediments drilled from five sites at the bottom of the Atlantic Ocean strongly supports the notion that one massive hunk of space rock caused the mass extinction, a research team led by University of Missouri-Columbia geology professor Ken MacLeod found.

"It's a completely straightforward, single-impact scenario," MacLeod, whose findings appear in the Geological Society of America Bulletin, said in an interview. "It was a haymaker that nobody saw coming. One shot, and that's all you need to explain it."

Scientists believe that an asteroid about 6 miles wide hurtled to Earth 65.5 million years ago at the end of the Cretaceous Period, plunging into what is now Mexico's Yucatan Peninsula to carve out the Chicxulub (pronounced CHIK-shu-loob) crater measuring about 110 miles across.

4. I'm quitting tomorrow......was going to quit today but had to change...

...the clutch on my Ford Ranger and was afraid I'd smash something if things went lousy.

I started back smoking after quitting for 6 years but still remember the last time I quit.
(I almost threw my 12 inch Reflector across the Yard! ...because of my shitty mood.. LOL!

6. I remember reading about a hit in the North Sea...

And a number of others in the Yucatan area. All within a 100k yr window suggesting a scenario similar to the way Jupiter got hit in the early 1900's.

7. I'm not buying that...

Where are the samples from the Pacific, or the the Indian Ocean, or The Urals, or Antarctica? It's like going out into my garden, finding that it's raining in five different places, and concluding it's also raining in Kenya.
