All right, the theory is appealing but wait a minute--there have been other
spectacular mass extinctions in the past. What about the Permian one, for
instance? Unless there exist meteorites that home on areas with sulfur-rich
evaporites, the explanation must be a unique one for a unique event, and other
mass extinctions must have entirely different causes. I remember someone
suggesting paleoweltschmerz...
