Re: Warm vs Cold blooded

   Didn't Horner in Digging Dinosaurs (or his student at the time, Mary
something,) determine that the bone growth of Maiasaurs seemed to represent
warm-blooded growth traits as juveniles and cold-blooded growth traits as
adults?  Wouldn't this sort of evidence lend itself to an interpretation that
dinosaurs could be both?  Or change from one to the other over time?  How
likely is this bone-growth effect to happen in something other than Maiasaurs
in specific, or hadrosaurs in general?
