Re: Hell Creek -- MYSTERY SOLVED: How the dinos died!. :o)

    Of whether the ozone layer was damaged or removed, David Marjanovic
said:

    "Probably it was. The impact must have created large amounts of nitric
oxides
and blasted them far upwards. Should destroy the ozone layer immediately
according to apparently unpublished calculations. :-} BTW, nitrogen dioxide
(and the monoxide becomes dioxide pretty soon) is deeply reddish-brown
[FREEZE], while dinitrogen monoxide = laughing gas is a powerful greenhouse
gas [BAKE]. :-)"

    In that case, the mystery is solved!  The dinosaurs died laughing!  :-o

    Sorry, I couldn't resist.  ;o)
