DescriptionDifferent skull shapes can represent the same dinosaur at different ages. As the dinosaur grew, the nasal bones in its skull expanded to form the tall hollow crest that characterizes the adults. A baby Lambeosaurus had no crest, whereas a full grown adult had a large crest. This individual was half-grown and has a partially developed crest. The hollow crests may have been used as resonating chambers for calling to one another. Differences in the shape and size of crests would help the duck-billed dinosaurs, or hadrosaurs, to recognize their own species.
