I hope the rest of the science media is ignoring the mammoth-killer impact for the same reason I am, because it has been shown there is no science to support it. My September 3, 2010 story in Science, Mammoth-Killer Impact Flunks Out, reported that 3 years after the idea was introduced at the AGU in Acapulco, just about every outside expert who had put their time, money, and energy into checking the evidence in their specialty was thoroughly disgusted with the whole thing. Nothing was checking out. Ordinary materials had been interpreted as evidence of impact. They were washing their hands of it. True, advocates have gotten a couple more papers in PNAS, but a paper by other outsiders recently in PNAS came up with the same years-old conclusion–there is no evidence for impact. End of story, at least for me.

Richard Kerr of Science
The best that I can say for Dr. Kerr is that he may be trapped in an echo chamber without access to scientific publications.
Below is a less formal but informative riff prepared by Mr. Dennis Cox, who was forced by lightly informed geeks to publish his writing in Wiki’s “Talk” section, where you are welcomed to argue it with lightly informed geeks.
Quite a few of your refs are preprints / conferences (e.g. XVIII INQUA-Congress). Those don’t really count – anyone can say anything at a conference. You need to strip those (and any other grey lit) out of your list William M. Connolley(talk) 16:27, 19 April 2012 (UTC)
I will be editing the list over the next couple of days. But on the subject of anyone being able to say anything, it should be noted that every one of those people on that list are multiple PhD scientists who are doing real science, working and speaking from their own actual experience, and knowledge. And since SkepticalRaptor set the bar for providing reliable reference in this particular debate in his appeal to authority of some anonymous people he only describes as “some people smarter than me” I’m thinking that list is looking pretty darn good for the time being.–CometHunter (talk) 17:21, 19 April 2012 (UTC)CometHunter
