Re: Dinosaur extinction

In a message dated 98-02-20 03:21:16 EST, you write:

<< A worldwide cold spell over the course of a few centuries, maybe just a few
 years, would be a disaster for nearly all animals.  While high-latitude 
 dinosaurs may have been able to migrate towards the equator, their food 
 plants couldn't.  Regardless of whether they could survive the cold, large 
 animals like dinosaurs would not have enough food to survive.  If dinosaurs 
 were warm-blooded, they would have needed about ten times as much food as a 
 crocodilian of the same size. >>

Makes sense but what about mammals why wouldnt this hypothesis 
work for them as well. How did they get though the ice ages?
What food sources did a Mastodon depend on (It would need extremely large
quantities as well). What makes cretaceuos plants any different? after all
they were similar to modern plants. It seems unlikely that a few species
couldnt survive.

personally I accept the meteorite impact theory It seems has the most evidence
to back it. Plus if some crocodilians had the ability to hybernate there it is
more likely that at lest some of them would get through. But what about the
sea animals plesiosaurs and mosasaurs.  It never ends
