Microscopic meteoritic ablation spheres recently found on top of the Victoria Land in Transantarctic Mountains, and in the L2 Dome C and DF2691 Dome Fuji ice core layers document a major impact of a 108kg (or larger) cosmic body in the Antarctic region about 480kyr ago. Although of broadly chondriti...
