"The Daulton et al claim that we have misidentified diamonds is false and misleading," he said. And geoscience consultant Allen West added that Daulton and colleagues had not followed the same protocols and therefore it was no surprise they had came up with a blank. "They looked at charcoal but we never mentioned that we ever found diamonds in the charcoal," he told BBC News.

Doesn't look like this debate is at all settled.

This is the same kind of slingin-it BS that went on regarding the K-T impact extinction scenario. I’ve begun reading a remainder copy of “Gorgon”, which is about the P-T mass extinction. Its author is the coauthor of some books I don’t much care for, and this one appears to end stupidly, but it was nice to read the reminder that ALL the so-called controversies and questions and counterclaims against the K-T impact model were buried by the scientific research by the author and many others like him.

There are still some already-discredited (some of which were born discredited) objections to the K-T impact model that perk back up. The one thing the authors of the mammoth mass extinction book have against them is, the event is very recent, well within the time of modern humans, and for that matter, is the same event which ended the Clovis culture.

IMHO, they do an outstanding job with their scientific stuff, other than perhaps the nature of the impact itself (I disagree with them a little, not that anyone listens to me), and do a pretty good job integrating it with surviving folklore of various American tribes.
