Parasaurolophus Sounds

Turn up the speakers! I found this clip the other day and made a video around it. I remember seeing a show about this a long time ago, but forgot about it (and honestly wasn&interested at the time). I happened to be doing some researching and found this audio clip of what they made and discovered. I personally find this amazing. Notes: obviously I do not have the privilege of studying dinosaur fossils, so the part about the brain is what I&heard from TV shows. The recreated sounds is, as stated, with alternate versions (such as with or without voice box) and/or different ways the animal was able to pitch of the sound.
