Dinosaurs were hot-blooded creatures, claim scientists who measured their body temperatures for the first time

Giant four-legged dinosaurs were not cold-blooded as previously thought, but had body temperatures similar to those of present-day birds and mammals, a study has found.
But scientists are still trying to work out how they kept cool.
The findings, based on studies of fossilised dinosaur teeth, lend support to the idea that dinosaurs were warm-blooded creatures which regulated their body warmth.
