“It’s exciting to apply our studies of living animals back to the fossil record to test different evolutionary scenarios,” Herman Pontzer says. “Our results provide strong evidence that many dinosaur species were probably warm-blooded,” he adds. “The debate on this issue will no doubt continue, but we hope our study will add a useful new line of evidence.”
WASHINGTON-ST. LOUIS (US)—Recent evidence suggests many dinosaurs may have been “warm-blooded” like present-day mammals and birds rather than cold-blooded like lizards. If true, their internal furnace would have enabled them to live in colder habitats, such as high mountain ranges and the polar regions, allowing them to cover the entire Mesozoic landscape. Continue…

“We could see changes to ecosystem structure and stability if cold-blooded species change their life histories to accommodate warmer temperatures but warm-blooded species do not,” says researcher Santiago Salinas.
