Heterotherm seems like an option,due to the lower food requirements,but
aren't dinosaurs thought to exhibit homothermy or near-homothermy as a
plesiomorphic feature? Do naked mole rats and ,possibly,crocodiles count as
heterotherms descended from homotherms?
I think so.
but, if I recall rightly, naked mole rats shiver - which is a homothermic
is there a shiver-thermy?
Then I remember there being a theory about sauropods being
gigantotherm,meaning that they maintained their body temperature by means
of their size and the warmth that automatically makes them keep,allowing
them to lead active,homotherm lives,without being homotherm themselves and
they would also circumvent the problem of the food requirements,of course.
But I do not believe there are analogs for something like that.
Also,wouldn't it mean that younger or smaller sauropods (Magyarasaurus for
example) had a metabolism they could not rely on?
maybe the young of the BIG ones (and likely adults of the smaller ones)
weren't gigantotherms...imho, that wouldn't keep the BIG adults from being
