Re: Why Did Mammals Survive the 'K/T Extinction'?

An additional factor not mentioned in the news article (but possibly in
their research) is that tiny mammals need only find a tiny bit of food in
absolute terms (grams), even if they need a relatively large amount (grams
food/grams of mammal) due to high metabolic rate. And it would have been
easier to find crumbs than a banquet.
