The bones of warm-blooded animals have more passages for blood vessels than those of cold-blooded critters. Therapod dinosaur bones have lots of passages for blood vessels (like birds or mammals) when compared to turtle or lizard bones, which have fewer passages for blood vessels.

Okay, you gave an explanation, let's see the proof of it. BTW does that mean that mammals descended from dinosaurs? Does that mean that evo paleontology has been proven wrong again?
