Spinosaurus had a long neck, strong clawed forearms, powerful jaws and the dense bones of a penguin. Now, 70 years later, a new skeleton found in Morocco reveals that the beast was far more aquatic than originally thought. The beast, called Spinosaurus aegyptiacus, was already known to scientists from a long-ago fossil discovery, but most of those bones were destroyed in Germany during World War II. This patchwork of critters, a 50-foot (15-meter) predator, is the only known dinosaur to live much of its life in the water.

The result gives one some idea of a bizarre dinosaur scientists unveiled on Thursday.

A 50-foot life-size model of a Spinosaurus dinosaur is displayed outside the entrance at the National Geographic Society.
