Paleontologists Nizar Ibrahim and Professor Paul Sereno published a groundbreaking article in the journal Science in September detailing a new skeleton of Spinosaurus, the largest known predatory dinosaur. To assist with their examination of the skeleton, Drs. Ibrahim and Sereno enlisted the help of radiologist Christopher Straus, M.D. and the Human Imaging Research Office to perform extremely detailed high-resolution CT scans of their fossilized specimens. These CT scans were used to create 3-D models of the individual bones, which were then used to create a complete skeleton and later a life-size model for a National Geographic exhibition. The project was covered extensively in the media by outlets like the Chicago Tribune and the New York Times.
