鸡哥影院提供恐龙是怎样炼成的全集完整版免费在线观看剧情介绍：Dinosaurs died out 65 million years ago and we have hardly ever found a complete skeleton. So how do we turn a pile of broken bones into a dinosaur exhibit? Dr Alice Roberts finds out how the experts put skeletons back together, with muscles, accurate postures, and even - in some cases - the correct skin colour. ----------（From BBC Four Programme Official Website）
