Parasaurolophus is easily recognizable due to the long, swept-back crest on its head. The crest contained a number of tubes that allowed Parasaurolophus to emit a low-frequency noise – a little like a foghorn. In addition, it is believed that the crest may have helped the creature to regulate its temperature and to attract mates. Parasaurolophus could walk on all fours or on two legs.
