The Scientists at Sandia National Laboratories and the new Mexico Museum of Natural History and Science have together to recreate the sound of one of the most recognizable dinosaurs Parasaurolophus. Sandia computer scientist Carl Diegert left and new Mexico Museum of Natural History and Science Paleontologist Tom Williamson confer at the computer as they put the finishing touches on the dinosaurs sound.
Computer modeling of the Parasaurolophus crest foreground reveals several tubes or air passages that run through it.
In the background is the crest fossil.
The study of dinosaur vocalization began after the discovery in August 1995 if a rare Parasaurolophus skull fossil measuring about
4.5 feet long.
Many scientists have believed the crest containing a labyrinth of air cavities and shaped something like a trombone might have
been used to produce distinctive sounds.
Base on the structure of the crest the dinosaur emitted a resonating low-frequency rumbling
sound that can change in pitch.
This very low frequency sound is called infrasound.
Its is proposed that each Parasaurolophus probably had a voice that was distinctive enough to not only distinguish it from other dinosaur but from other Parasaurolophus as well.
The sound is an Approximation of the possible tones the dinosaurs crest was able to produce.
The scientists and paleontologists had to use common sense and some imagination to reconstruct both missing parts such as the beak and nostrils and soft tissues of the head and throat that were fossilized.
