Birds, the last surviving dinosaurs, are warm-blooded. But scientists have long debated whether other dinosaurs were also warm-blooded like birds or were cold-blooded like reptiles. Now, in a new study published last week in the journal Nature, researchers find many dinosaurs such as Tyrannosaurus and Brontosaurus may have indeed been warm-blooded, as well as the flying reptiles known as pterosaurs and the Loch Ness Monster-like creatures known as plesiosaurs.
