Paleontologists in the region build relationships with locals to ensure that scientifically important fossils are brought to their attention. Spinosaurus was one of the largest predatory dinosaurs of all time. It is named for its elongated dorsal spine, which supported an enormous “sail” of skin. In contrast to other dinosaurs–which were predominantly terrestrial–a long list of anatomical features are indicative of Spinosaurus being adapted to live in freshwater, like crocodiles and hippopotamuses. #spinosaurus Follow paoloverzone for more photos and stories.
