I find the entire debate to be amusing.First of all, much of the evidence for warm-blooded dinosaurs dates from the late Creataceous (meaning just before the Big Dino Die-Off); likewise, most of the cold-blooded evidence dates from the Triassic and early Jurassic periods (the early Age of the Dinos). Is it possible in the 150 million year gap that dinosaurs evolved to become warm blooded, because warm-bloodedness has distinct evolutionary advantages (speed, high metabolism in a food rich environment)?Just something I've mused over a lot.
