The
world's third largest asteroid impact zone has been found in South
Australia. According to scientists involved, the asteroid, which
measured up to 20 km across, hit Earth approximately 360 million years
ago. This was around the time of the Late Devonian mass extinction,
strengthening the idea that asteroid impacts have been associated with
many mass extinctions throughout the history of life on Earth.
