A real weird news story from Nature about meteor damage to pleistocene fossils:
http://www.nature.com/news/2007/071212/ful...s.2007.372.html If traces of this meteor shower has been found in both Siberia and Alaska as the story implies, then multiple impactors must have been involved. Such small meterites would lose speed quickly so the airburst must have occurred at fairly low altitude. |

Yeah - the maths of this makes the likelihood of a particle of that size, traveling fast enough to do that damage very very small.
