Have archaeologists found masses of unburied skeletons human and animal in North America dating from that era?

Hi Dave, 
  
It would appear to me that you are basing your conclusion on what is presented in this story (which is definitely poorly written) and not on the study itself. The study which was just released (perhaps a preview was released weeks or months ago) has not had time yet to be rejected by other credible scientist. 
 Heck, the study itself might just contain the evidence this jury you referred to has been waiting for. 
  
Just a though.

Didn't this come out several weeks (months?) ago? I wonder why they're trotting it out again. Maybe a tie-in to the black spot on Jupiter, though we all know that that is a sign that the planet is being stellified.
 
The headline contradicts the contents of the story - never a good sign. There's a lot of doubt out there in the community about this interpretation of the data. Heck, that there was a human die-back at the Younger Dryas is up for debate. And, most quaternary scientists I know are perfectly happy with assigning responsibility for the megafauna die-off to climate change (mainly) and overhunting (though that remains more controversial). No third cause needed. If impacts did occur, why comet impacts? In the story they say "comet-like objects." What does that mean? Asteroids? 
 
This doesn't mean that this interp is wrong, necessarily, just that the jury is still out. My criticism here is aimed at the news story, not at anyone posting here or their deeply held beliefs.
