"Beyond T-Rex"

["Tomporowski, Steve" <Steve.Tomporowski@us.ms.philips.com>]

I watched "Beyond T-Rex" last night on Discovery (thanks again for the 
heads-up, Larry) and while I was disappointed is in the lack of 'real' 
information, I was really surprised by the pronunciation of the two 
"challengers'" names.  Now I admit that I never tried to pronounce them, but 
instead of Giganotosaurus sounding like "gigantic", they pronounced it like 
it was the Irish dancing dinosaur while Carcharodontosaurus sounded that the 
coughing dinosaur.  Were these the preferred pronunciations?  Or should they 
sound different?
