Scientists have discovered strange emerald green rock in England that they believe originated in Quebec and was blasted over to Britain by an asteroid or comet that slammed into Earth millions of years ago.
The tiny spherical rocks are so bizarre, and alien to the region near Bristol where they have been found, that geologists say the most likely explanation is they are debris from the Manicouagan crater in northeastern Quebec.
"It seems we've got bits of Canada spread across Britain," said Professor Gordon Walkden, of the University of Aberdeen, lead author on a report on the discovery in the journal Science today.
The Manicouagan crater is one of the largest and oldest on Earth.
Scientists believe the crater, which measures 70 kilometres across, was created when an asteroid or comet barreled in from space 214 million years ago and smashed into northeastern Quebec with the force of 40 million Hiroshima bombs...
