The crater, buried beneath a half-mile of ice and discovered by some serious airborne and satellite sleuthing, is more than twice as big as the one involved in the demise of the dinosaurs. I didn't know that the "dinosaurs were killed by a meteor" theory had graduated to fact.
To: cogitator
The newfound crater is more than twice the size of the Chicxulub crater in the Yucatan peninsula, which marks the impact that may have ultimately killed the dinosaurs 65 million years ago. The Chicxulub space rock is thought to have been 6 miles wide, while the Wilkes Land meteor could have been up to 30 miles wide, the researchers said.

A 30 mile wide chunk can leave a mark.
That it is under a thick layer of ice and they can still detect it is pretty cool.
Why 250 million years ago. and what else lies out there.. not sure. we need more spaceborne instruments, more eyes on the sky, it's a busy place out there, stuff flying all over..

If you're an Ohioan, the definite article i.e. - "The Ohio State University" - is seen as trying to be uppity by regular folks. Hence my post.
We have plenty of football players, thanks.

Tekeli-li! Getting our geologic information from the Necronomicon are we?

I didn't know that the "dinosaurs were killed by a meteor" theory had graduated to fact.That statement had good wording, because some of the absolute most recent K/T boundary research is downplaying the likelihood that the Chicxulub crater caused the extinction of the dinosaurs, and the climate change + increased volcanism theory is regaining lost ground.
To: akorahil
Sorry, didn't read it. Just thought it was amusing and looked the creature up on the Internet. Sounds like you are recommending it. I will look for it at the book store.

Asteroid or comet triggered death of most species 250 million years ago

Earth's most severe mass extinction - an event 250 million years ago that wiped out 90 percent of all marine species and 70 percent of land vertebrates - was triggered by a collision with a comet or asteroid, according to new findings by a team led by a University of Washington scientist.
The collision wasn't directly responsible for the extinction but rather triggered a series of events, such as massive volcanism and changes in ocean oxygen, sea level and climate. Those in turn led to species extinction on a wholesale level, said Luann Becker, UW acting assistant professor of Earth and Space Sciences.
"If the species cannot adjust, they perish. It's a survival-of-the-fittest sort of thing," Becker said. "To knock out 90 percent of organisms, you've got to attack them on more than one front."

It is so hard to take "scientists" seriously these days.Right. Our religious leaders have done so much to explain the observable.
