Brown was inspired and immediately started working in his first project, Rawr! A study of Sonic SkullsIt is the work that the dinosaur chorus continues. Both projects focus on Corythosaurus, but at different stages of their longevity to investigate how changes to the peak in adult maturity affect their sound. However, the biggest difference between the two projects is the sound created, the reconstruction of the dinosaur's voice box.
Rawr!, We used mechanical larynx, so people will have to actually blow into the suck tube to make sound. But once we started to show it, we realized that people would not interact with it.
The work in the dinosaur chorus officially started in 2021, with Brown traveling to Canada, where Corythosaurus was thought to have lived, to update his research. She and Gajewski worked with the ancient biologist Thomas Dudgeon, from the University of Toronto and the Ontario Royal Museum, to analyze the most recent CT and 3D scanners. From those people, they built a real -sized copy of one end of Corythosaurus adult, even to its complex nose.
I am extremely proud of my nose, Brown joke. I have learned the CT segment for about a year to get them as accurate as possible, considering the impact buried for millions of years will also have for them.
With the complete skull model, the work later started on the dinosaur pronunciation. With the voice box currently in calculation, it gave Brown more control to check the new research and may even conflict without having to rebuild everything from the beginning.
Models are based on a set of mathematical equations related to the voice of the voice, things like changing air pressure and some other affected variables over time, she said. I have found a number of models in literature and put them in the most recent research code.
In particular, Brown is inspired by a paper Looking at an ankylosaur larynx, it was only found in 2023. It made researchers hypothes out that dinosaurs were not a bird like a bird (in the chest), and not the larynx of mammals and crocodiles (lying in the throat), as the first time thinking.
