Which dinosaur is known for its long, backwards head crest?
Correct!
Parasaurolophus was a herbivorous duck-billed dinosaur that lived in what is now North America about 76 to 74 million years ago in the Late Cretaceous Period. His long, backwards-pointing head crest was particularly noticeable. The comb was hollow. According to the Natural History Museum, an empty channel ran from the nostrils through the ridge, looped at the end, and returned to the skull. Scientists believe the comb may have had multiple functions. Among other things, Parasaurolophus could have used it to produce deep, trumpet-like sounds in order to communicate with members of its species. The recognition of other animals and the regulation of body temperature are also discussed.
Parasaurolophus is particularly known for its long, hollow head crest, which was probably also related to sound production and communication.
