Large dinosaurs would presumably have had to deal with similar issues; their body size suggest they lost
heat relatively slowly to the surrounding air, and so could have been what are called inertial homeotherms,
animals that are warmer than their environments through sheer size rather than through special adaptations
like those of birds or mammals. However, so far this theory fails to account for the numerous dog- and
goat-sized dinosaur species, or the young of larger species.
