guardian.co.uk : Tyrannosaurus rex was an athletic, warm-blooded animal that jogged rather than lumbered around its territory, according to a new study.Researchers led by Herman Pontzer at Washington University in St Louis examined the anatomical details of 14 dinosaurs of different sizes to work out how much energy the animals might have needed to move around.He found that, for dinosaurs weighing from a few kilograms to tons, the power their muscles needed was far too high for the animals to have been cold-blooded.
