The possibilities whether dinosaurs were active, warm-blooded animals, had parental care, and the theory that they are the ancestors to birds are featured.
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.
Some physiological activities, particularly responses, in human beings and other warm-blooded animals can also be monitored with thermographic imaging.
