Researchers have developed a new way of determining the body temperatures of dinosaurs, providing new insights into whether dinosaurs were cold-or warm-blooded.
A paper co-authored by Colorado College Associate Geology Professor Henry Fricke discusses the techniques used to determine the body temperature of animals that have been extinct for 150 million years.
By analyzing the teeth of sauropods — long-tailed, long-necked dinosaurs that were the biggest land animals ever to have lived — the scientists found that these dinosaurs were nearly as warm as most modern mammals.
