James Passas  asked the Naked Scientists:
   
Hi Chris,
 
It was interesting to hear the professor's explanation for why crocodiles have survived unchanged for hundreds of millions of years, through being well adapted to their niche.  
 
But why weren't they wiped out at the same time as the dinosaurs, when a comet hit the Earth, or whatever the reason was?  Could it be something to do with their aquatic environment offering some protection from the effects?  
 
Kind regards,
 
James in Cambridge.

What do you think?

I was thinking, another possible explanation for why crocodiles weren't made extinct by the cataclysm which wiped out the dinosaurs, could be their diet.  Maybe the dinosaurs had a more specialised diet, so when their specific food source was wiped out, they starved.  Crocs, being less fussy could probably have survived on more diverse food sources?

Mmm - interesting point; obviously, sharks are still around today and they're pretty ancient (I think Diana made this point), so there are some species that survived the downfall of the dinosaurs, we just don't know exactly why...
