Very true. But they are poor analogues for dinos nesting in cool climates
They lay and then leave their nests. Perhaps because
they are inattentive parents they cannot affect the incubation temp.
Therefore they must lay in very warm temperatures.
Also, their eggs take much longer (at least than bird eggs) to hatch.
Cold climates have shorter periods of warmth.
