Corythosaurus reconstruction

Oct 16, 2008

Reconstructions of the skull in a juvenile and sub-adult Corythosaurus created using CT scanning. The nasal cavity is highlighted in green, and the brain appears in purple. The complicated nasal passage within the showy crest functioned as resonating chambers during vocalization. The structure of the inner ear and expanded brain confirms that duck-billed dinosaurs were capable of perhaps sophisticated behavioral communication.
