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

>>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.

An equally instructive question would be, "why did *birds* survive the
K/T extinction?"

It seems like Dr. Holtz' explanation is at least as good an explanation,
if not better, for why birds survived but large dinosaurs did not.
