Re: back to science
I have only one or two comments to add to an otherwise excellent
prognosis of the evidence, Dave, and while scarce, there is a lot to
said from so little "hard fact" if a person looks close enough, or even
pulls back to look at the whole picture. You've done this.
<..The extremely large size of adult sauropods combined with their
Jim Farlow gives a good argument on why endothermy would be
detrimental to a sauropod's survival (it would overheat, basically, buit
he goes into greater detail elsewhere (somewhere on the list, I think,
as well as TV)). But even being an ectotherm, where I feel a slight
agreement in Jim's direction, the animal would still require the food,
and mass would give heat. Mass ectotherms, like green sea turtles, whose
sheer volume and mass give it an otherwise endothermic ability to
survive at cold and warm environments.
Being ectothermic in no way detracts from the rest of your theory.
<...This precluded a lay them and leave them strategy. (Actually, no
living archosaur descendant to my knowledge has such as strategy, so it
is doubtful whether any dinosaur did.)>
The cuckoos have that "lay 'em and leave 'em" habit, for which they
are singularly famous.
Anyway, great work, Dave.
