:: : : It sounds like the question is more relevant to Poikilotherm and Homeotherms rather then cold or warm blood.

For example, while smaller dinosaurs may have been true inertial homeotherms, or that many dinosaurs could have had intermediate metabolic rates.

:Most mammals ( and most birds ) are endothermic homeotherms ( traditionally, but inaccurately-" warm-blooded " ).
14.
:It depends, in part, whether the Ectotherm / poikilotherm was warmer or colder than the homeotherm at the time of the competition.

For example, while smaller dinosaurs may have been true endotherms, the larger forms could have been inertial homeotherms, or many dinosaurs could have had intermediate metabolic rates.
16.
Eggs are then sequestered within the portal system ( or perivesicular plexus in some species ) of homeotherms which restricts egg dispersal but limits the resulting pathology to less sensitive organs.
17.
However, endothermic homeotherms ( the animals generally characterized as " warm-blooded " ) both produce more heat and have better ways to retain and regulate it than other animals.
18.
Others like McNab and Geist suggest that the tapinocephalids were better considered inertial homeotherms, with the large barrel-like body and short tail being the most efficient surface for conserving heat.
19.
However, when homeotherms and poikilotherms have similar niches, and compete, the homeotherm can often drive poikilothermic competitors to extinction, because homeotherms can gather food for a greater fraction of each day.
