Saurolophus, a huge representative from a group of duck-billed dinosaurs. Discovered in 1948 by the expedition of the USSR Academy of Sciences. The bones of the skull roof of Saurolophus form a long narrow ridge, directed backwards and up. Its purpose is still a matter of controversy among researchers. Perhaps it served as a sound resonator. The ends of the jaws are strongly flattened, during its lifetime have been covered with a horn coating, like a beak of a duck or a platypus. There are four dozen rows of flat teeth in each half of the jaw - about a thousand teeth in total, being replaced during a lifetime. Saurolophus fore feet were sufficiently well-developed and could be used for support and movement.
