The difficulty with the Cretaceous extinctions has always been explaining
the demise of half the species on the Earth at the time, including plants,
phytoplankton, fishes, etc. etc.  Getting rid of just the dinosaurs is
(relatively) easy.  The impact theory has the merit of explaining all
of these extinctions with a single event we know for a fact can happen.
   I think we know for a fact it did happen;  Luis Alvarez has an article
on the current status of the impact theory in the July _Physics Today_.
Must reading, and accessible to lay persons.
