we can get a good idea of most through nasal cavities if we have a fossilized skull and then though the first few vertebrae where we can figure out how the neck muscles attached. Hadrosaurs are the hardest, just cuz of how most of their nasal cavities are constructed (you can get different pitches depending on flexing of muscles and the exhale, but most prolly sounded like a tuba or trombone). A T-Rex probably couldn't roar, but I like to still think one could. For something that big and that slow, it was most likely an ambush predator and scavenger, and possibly a family pack hunter it prolly sounded more like a crow.
