 * Support - nice to see it all rejiggled and settled this way. cheers, Casliber (talk · contribs) 23:37, 30 August 2007 (UTC)
 * Comment - I may be way off-base here (and if so, feel free to attempt a pickoff throw), but I'd be interested in a brief treatment of the historical development of thought on the topic, with points like the recognition that it occurred, the old hypothesis that mammals had replaced dinosaurs because the latter had gotten stagnant, the appearance of Alvarez's work, etc. If  anyone else is interested and thinks it's applicable, I'll see what I can find. (Actually, it would also be interesting to have somewhere (not in this article, probably) a description of the numerous rejected theories, many of which fail because all they attempt to explain is dinosaur extinction.)

 * That's a very good suggestion. A nice para on it with a ref should do the trick nicely. cheers, Casliber (talk · contribs) 03:20, 31 August 2007 (UTC)
 * I don't think absence of such information should hold it up, though; it would just be gravy, and it may take some time to find the proper references. J. Spencer 21:52, 31 August 2007 (UTC)
 * As the main editor for this article (I don't quite know how that happened), I tried to separate the event from the cause of the event. I like the suggestion on a history of theories of the event, but as soon as we have this article FAC (or close), I want to take that suggestion and use it to improve K-T boundary, which describes the geological causes of the extinction.  That the extinction happened is without controversy.  That some environmental event caused the extinction is also without much controversy (unless, of course, you're some sort of Creationist)).  That the environmental event was caused by......., well that's a story to be told.  Orange Marlin  Talk• Contributions 05:47, 1 September 2007 (UTC)


 * Comment I have trouble with this sentence from the lead: "Mammalian and bird clades passed through the boundary with few extinctions, although radiation occurred well past the boundary." I understand what is meant here: the current diversity of mammals and birds did not develop until after the extinction event. However, using 'although' to connect the two phrases here seems wrong to me; the two facts aren't that closely connected and the radiation event isn't a qualification to the statement about mammalian and avian extinction. Hope that makes sense! 4u1e 07:28, 31 August 2007 (UTC)
 * Good suggestion. "And" is the proper word, I believe.   Orange Marlin  Talk• Contributions 05:49, 1 September 2007 (UTC)


 * Support I think this article provides good coverage of an important subject. If any Subject Matter Experts are here and have suggestions for improvement, I would implore them to make concrete, substantive suggestions, and not just vague general statements.--Filll 13:29, 1 September 2007 (UTC)
 * Support Great source of information on the subject, very much featured quality. Hello32020 23:13, 2 September 2007 (UTC)
 * Support A wonderful report of one of our greatest mysteries. A good read and great content depth. aliasd·U·T 11:38, 3 September 2007 (UTC)
 * Support I'm willing to throw in at this point. Let me know if you need anything; I'll probably continue to pick at it, but there's nothing objectionable as far as I'm concerned, mainly stylistic concerns. J. Spencer 21:16, 3 September 2007 (UTC)
