Learn how scientists used a digital model to reconstruct Spinosaurus in this video from NOVA: Bigger Than T. rex. The first Spinosaurus fossils were found in Egypt in 1912 and described by German paleontologist Ernst Stromer in 1915. However, those fossils were destroyed overnight in 1944 during a World War II bombing. To preserve images of a newer Spinosaurus skeleton, researchers at the University of Chicago used a CT scanner. They then used Stromer’s Spinosaurus drawings and scans from Suchomimus (a close relative) and bones from other specimens to form a more complete model. The complete digital model revealed Spinosaurus to be about 50 feet long.
