Dinosaur cold-blood theory in doubt

http://www.bbc.co.uk/news/science-environment-18602965



One of the strongest lines of evidence that dinosaurs were cold-blooded, like modern reptiles, has been knocked down.

Prior studies of dinosaur bones uncovered what are known as "lines of arrested growth".

The creatures were presumed to be cold-blooded because modern cold-blooded animals show these same lines.

But scientists reporting in Nature have studied the bones of 41 modern mammal species from around the world, finding every one had these lines as well.
