Parasaurolophus crest resonance, reconstructed call
A modelled low-frequency call derived from the crest's internal airways. A reconstruction, not a recording.
76.5 to 74 Ma · Dinosaur Park Formation, southern Alberta, Canada · CTF-PAL-000002

- Method
- Crest resonance modelling
- Built from
- Parasaurolophus walkeri holotype, ROM 768 T1 Recorded
- Confidence
- Moderate confidence in the resonant frequencies (within about 20 percent). No confidence in timbre, rhythm or loudness, which are unknowable from the fossil.

Synthesised low resonant tone representing the modelled crest frequencies. Placeholder audio.
About this record
The nasal passages of the crest were modelled as a resonating tube and its fundamental and first harmonics were synthesised. The result shows what frequencies the crest could have favoured. It cannot show what the animal actually sounded like, how loud it was or when it called.
