 In other words, the thermal capacity of such large animals was so high that it would take two days or more for their temperatures to change significantly, and this would have smoothed out variations caused by daily temperature cycles.This smoothing effect has been observed in large turtles and crocodilians, but "Plateosaurus", which weighed about , may have been the smallest dinosaur in which it would have been effective.Inertial homeothermy would not have been possible for small species nor for the young of larger species.
