The scale compares the named dimensions. View direction and measurement points are given for each animal.
Parasaurolophus walkeri was a Late Cretaceous North American herbivorous hadrosaur. It had a broad beak and long bony crest projecting behind the head. Internal passages connected to nasal airways formed an elongated route for airflow.
This structure may have amplified sound and supported communication. Recognition and display functions have also been considered. Models of possible calls are approximations based on passage shape, not recordings of actual sounds.
Extensive dental batteries processed plants, with replacement teeth renewing worn surfaces. It could walk on four limbs and raise its torso onto the hindlimbs. Parasaurolophus species differed in crest shape, so one species' anatomy should not be directly equated with all others.
