But it is also possible to work off of authenticated scale models of the dinosaurs that have been created by the paleontologists Mammoths and Mastodons of the Ice Age Science 283 (January 1999): 468. "Cold-blooded" animal; an animal that relies on the outside air temperature to regulate its body temperature; ectotherms (animals that are ectothermic) have a low metabolic rate.
