"Our results suggest that all major groups of dinosaurs had warmer body temperatures than their environment." 'Ancient thermometer'By looking at the order of oxygen and carbon atoms in the fossilized egg shells, the researchers were able to calculate the dinosaur mom's internal body temperature. They found that the samples they tested suggested that the dinosaurs' body temperatures were warmer than their surroundings would have been. So unlike reptiles, which rely on heat from the environment, the research indicates that dinosaurs were capable of internally generating heat. The different dinosaurs varied in how much their body temperatures were higher than their environment.
