James Gurney demonstrates the stepbystep process of painting two restorations of the dinosaur Spinosaurus under the direction of Dr. Paul Sereno of the University of Chicago.

Dr. Sereno's scientific paper in Nature Magazine is called "Spinosaurus is Not an Aquatic Dinosaur." Sereno's team developed a CTbased skeletal restoration of Spinosaurus and examined its hydrodynamic properties. They found that the digital model of Spinosaurus performed very poorly in water, supporting the alternative "semiaquatic hypothesis." In an interview, Sereno said, "I don't think it was a good swimmer nor capable of full submergence behavior."

Coauthors include Donald M. Henderson, Daniel Vidal, Frank E. Fish, Stephanie L. Baumgart, Tyler M. Keillor, Kiersten K. Formoso, Nathan Myrhvold, Lauren L. Conroy .
