恐龙是怎样炼成的上映时间：2011年
电影恐龙是怎样炼成的是一部由艾丽丝·罗伯茨联合主演，Oliver,Bootle执导英国纪录片电影。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）
