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't 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've 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.
