Re: Cold-blooded vs. warm-blooded (LONG REPLY)



Could you hazard a guess at how the dinosaurs would have
responded--relative to other creatures--to abnormally high temperatures.
Would they have been at a relative disadvantage if, say, the temperature
increased 10C over previous highs for an extended period of time?  And
thank you for informative post.
