Arizona State University Doctoral student Courtney Brown wanted to find out what kind of sounds a Corythosaurus might have made as its mating call. The way that the dinosaur produced sound is intimately connected with the interior spaces and solids in its skull and so she used CT scan data in order to generate a digital replica of the skull. She used a 3D printer to create the nasal passages and crafted the rest of the skull out of foam using a machining tool. By blowing air in through the larynx of the replica, we can hear, for the first time in 65 million years, what the dinosaur might have sung to attract a mate.
