Greatest Mass Extinction On Earth Discovery

A giant crater, roughly the size of Ohio has been discovered in Antarctica. It is believed that this impact is what caused the greatest mass extinction in the history of the earth 250 million years ago.

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.


The crater's location, in the Wilkes Land region of East Antarctica, south of Australia, suggests it might have instigated the breakup of the so-called Gondwana supercontinent, which pushed Australia northward, the researchers said.


"This Wilkes Land impact is much bigger than the impact that killed the dinosaurs, and probably would have caused catastrophic damage at the time," said Ralph von Frese, a professor of geological sciences at Ohio State University.

It is suspected that the asteroid which killed off the Dinosaurs was roughly 6 miles wide, while this new discovery is suspected to have had an asteroid approximately 30 miles wide.
A pretty amazing find.

I guess this is one "good" consiquant of "Global Warming.

Thanks.
