Workers grind the rough edges off an anatomically precise, life-size Spinosaurus skeleton created from digital data. Scientists assembled a computer model from CT scans of fossils, images of lost bones, and extrapolations from related creatures, then expressed it in polystyrene, resin, and steel. | Mike Hettwer/National Geographic, from the October edition of National Geographic magazine. Spinosaurus will be the subject of a new exhibition at the National Geographic Museum in Washington, D.C., opening Sept. 12, as well as the topic of a National Geographic/NOVA special airing on PBS Nov. 5 at 9 p.m.
