The dinosaur fossil unearthed here is the most complete Cretaceous theropod ever found in North Africa. Spinosaurus was one of the largest predatory dinosaurs of all time. It is named after the elongated dorsal spines that supported an enormous “sail” of skin. In contrast to other dinosaurs—predominantly terrestrial—a long list of anatomical features are indicative that Spinosaurus was adapted to live in freshwater, like crocodiles and hippopotamuses.
