       I recall reading this brand-new theory, and enjoying it, in a science 
fiction anthology over 20 years ago.

       Where's the crater?
       Where's the explosion ejecta?
       What isotopic signatures does he predict for the re-impacted debris? I 
would think off the top of my head that a violent run-away of a fusion 
reactor would result in high (if brief) neutron fluxes, so I'd predict an 
excess of neutron-rich species in the stable isotope profile for the ejecta. 
But I'm not a nuclear physicist, so I'll defer to one (do any of the 
academics here know a nuclear physicist who they can ask over lunch on 
Monday) on that.

       This is directly contradicted by the observed fossil history of the 
Cetacea. As well as by their ankle bones and blood. Since this developing 
story has been one of the "poster children" of palaeontology for the last 25 
years, then either Aulicino is deliberately writing a fiction (see my 
previous comment about enjoying dinosaur SF, even that East of Eden dreck by 
the Harry 'Rattus ferroinoxidans' Harrison), or has been living in a barrel 
for the last 25 years.

       I think it's a good basis for an interesting SF story. It shouldn't 
exceed Dodgson's "six impossible things before breakfast" credibility limit, 
so there's a reasonable chance of it being more entertainment than the 
average quantum cryptanalysis paper (which typically require 10 or even 12 
pre-prandial impossibilities).

       I've seen "2 Million Years BC" - you'll never convince me that a stone 
age race with TB vaccination could ever be eaten by a 40m long chameleon.
