A huge crater was found in the east antartic that indicates a major meteor hit the earth about 250 million years ago. This one is much larger then the
one that may have killed off the dinosaurs, up to 4-5 times the size. Chicxulub crater, believe to have killed of the dinosaurs was caused by a meteor
about 6 miles wide, this Wilkes meteor would be about 30 miles wide. The crater is 300 miles wide.
Columbus, (Ohio), June 2: Planetary scientists have found evidence of a meteor impact much larger and earlier than the one that killed the dinosaurs
-- an impact that they believe caused the biggest mass extinction in Earth's history.
The 300-mile-wide crater lies hidden more than a mile beneath the East Antarctic Ice Sheet. And the gravity measurements that reveal its existence
suggest that it could date back about 250 million years -- the time of the Permian-Triassic extinction, when almost all animal life on Earth died out.
Its size and location -- in the Wilkes Land region of East Antarctica, south of Australia -- also suggest that it could have begun the breakup of the
Gondwana supercontinent by creating the tectonic rift that pushed Australia northward.

all I can say is holy hell thats huge. Something that big must have been extremely damaging to everything on the planet. I cant begin to imagine the
damge something like that must have done. Trying to imagine the meteor that wiped out the dinosaurs is hard, but this is even bigger. The idea this
may have caused australia to have shifted and broke away is simply amazing. It shows just how destructive and damaging something like this can be.
Its being tied to the worst mass extinction ever. this thing must have been massive. Imagine watching it come down and hit the earth from a viewable
distance. (might as well see it if its going to kill you anyway haha)
