Many dinosaurs were most likely warm-blooded with high metabolic rates that resembled those of modern-day birds, according to a study released yesterday (May 25) in Nature. “The question of whether dinosaurs were warm- or cold-blooded is one of the earliest concerns in paleontology, and now we think we have a consensus, that the majority of dinosaurs were warm-blooded.” The findings also suggest that endothermy cant totally describe why warm-blooded animals such as birds left the fate of the rest of the dinosaurs 65 million years back, though the paper does not provide an alternate description.
