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, I was thinking about what sort of model would work as well. The "shrapnel" hypothesis is thin as paper; if it can work at all, looks like it needs all sorts of very special circumstances. Still, can't think of anything better.
