Researchers from California Institute of Technology Take Dinosaurs Temperature with Teeth

LOS ANGELES (REUTERS).- Scientists in California say they have for the first time devised a way to accurately take the body temperatures of dinosaurs — by examining the creatures’ teeth. Chemical analysis of the Jurassic period fossil teeth from two sauropods — long-tailed, long-necked dinosaurs that rank among the largest land animals ever to roam the Earth — showed they were about as warm as most modern mammals. But they also were cooler than some experts had predicted for animals of such gigantic size. The findings from a team led by researchers at the California Institute of Technology were published Thursday in an online edition of the journal Science. “This is like being able to stick a thermometer in an animal that has been extinct for 150 million
