This video depicts the first instrument of Dinosaur Choir. The musical instrument is a replica of an adult Corythosaurus (ROM 1933).

Credits

Dinosaur Choir is created and coded by Courtney Brown. The design and fabrication of the physical dinosaur skull instruments is by Cezary Gajewski.

Paleontologist Thomas Dudgeon provided CT scans, 3D models, and consulting. David Evans also provided approval to use the CT Scans of the adult Corythosaurus (ROM 1933) for this project. We also acknowledge the Canada Fulbright, Ira Greenberg, Garth Paine, Scott Smallwood, Caleb Brown, Natalie Loveless, Phillip Currie, Corwin Sullivan, Howard Gibbons, and the rest of the University of Alberta Dinosaur Paleontology Lab for their support of this project and research.

Funding sources for Dinosaur Choir includes a Southern Methodist University Research Council Grant and United States Fulbright Scholar Award to Courtney Brown as well as a NSERC Vanier Canada Graduate Scholarship to Thomas Dudgeon.

This work builds upon the previous work, Rawr! A Study in Sonic Skulls. Rawr! A Study in Sonic Skulls created by, Courtney Brown and Sharif Razzaque. The CT scans of the subadult skull fossil (CMN 34825) were provided by Witmer Labs, Ohio University and scientific research guided larynx creation. We also acknowledge Garth Paine, Carlo Sammarco, Sallye Coyle, Brent Brimhall and Gordon Bergfors for their contributions and funding from Arizona State University GPSA

All photographs are currently of different versions of Rawr! The three top photographs are by Sharif Razzaque.

About Dinosaur Choir

Dinosaur Choir is a project exploring dinosaur vocalization. Outcomes include the web syrinx and 3D fabricated dinosaur skull instruments for exhibition and musical performance and participation. Our work will be made open source when possible.

The web-based dinosaur syrinx is based on a bird syrinx computational model developed by Neville Fletcher (1988) and it’s implementation was considerably aided by the published work of Tamara Smyth (2002). Corythosaurus measurements used to modify the syrinx were obtained by Thomas Dudgeon and further speculations are by Courtney Brown, based on hyoid and skull measurements of adult Corythosaurus fossils.
