Meteor evidence found in Antarctica - 250 million years old

A massive crater in Antarctica may have been caused by a meteor that wiped out more than 90 percent of the species on Earth 250 million years ago, a geologist said. The 300-mile-wide crater lies hidden more than a mile beneath a sheet of ice and was discovered by scientists using satellite data, Ohio State University geologist Ralph von Frese said WednesdayJUne 7, 2006.
