Today a girl in my drama class said “how did people know what dinosaurs sounded like? It’s not like they had a recording of them.” And just wow I never thought I’d have to deal with that….
It’s not that they new the exact sound, but using modern recreation technology and the bones that were found as remains (i.e. skull or chest) to different species, they were able to make a hypothetical guess as to what the sound may be using the constraints and likeness of creatures that exist in today’s world. Given that because certain parts of the dinosaurs decompose and do not remain the exact noise will likely never be known. An example would be the fact that if you can’t make an O with your mouth you can’t make the “who” noise. However, an owl has a flexible beak which allows it to do so, something that would not be apparent in it’s remains.
