[55] They appear to have remained prevalent in southern South America during the Late Cretaceous, where lizards remained rare, with their remains outnumbering terrestrial lizards in this region by ...
This unique feature is responsible for thermoregulation and hormone regulation, and possibly helps the lizards make decisions based on the seasons, weather, etc. [8] A March 2020 study of the central bearded dragon found that light-dependent magnetoreception occurs when light with a wavelength under 580 nanometers enters the parietal eye.
