Title: Asteriod impacts Written by: duddy on Feb 18, 2013 (https://biology-forums.com/gallery/47/4_18_02_13_1_04_57.jpeg) (https://biology-forums.com/index.php?action=gallery;sa=view;id=11365) The third largest asteroid to ever hit earth 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. |
