Sauropod dinosaurs, the enormous plant-eating dinos with long tails and necks, had body temperatures ranging from 96.3 to 100.8 degrees Fahrenheit -- making them as warm as most mammals -- including people. Because body temperature usually rises the larger an animal gets, the findings, published in the latest issue of Science, suggest huge sauropods had mechanisms for cooling themselves off. "What we can say is that sauropods did not have body temperatures that were as cold as modern crocodiles and alligators," lead author Robert Eagle... many models had predicted that sauropods would have high body temperatures of over 104 degrees......
