Parasaurolophus walkeri

Parasaurolophus walkeri

Parasaurolophus walkeri roamed Cretaceous floodplains on four legs while browsing low foliage, readily rising onto its hind limbs to reach higher branches or sprint from danger. Its iconic tubular crest enclosed an intricate loop of nasal passages that operated as an acoustic resonance chamber, projecting deep, low-frequency bellows across river valleys. Extensive batteries of hundreds of closely packed teeth ground tough, fibrous conifers and flowering shrubs into digestible pulp.
