Lambeosaurines were the crested hadrosaurids, with a clearly visible hook shaped pubic boot.
It has been possible to make a strong sound out of a crest cast of Parasaurolophus so
it's very clear that it had been possible to communicate with blowing a lot of air through
the cavity systems inside those crests, and create a powerfull horn sound.

These hadrosaurids has been found mostly in Asia and North America, and they
were normally around 10 metres long, and along with hadrosaurines
they lived in herds, and were most probably (based on fossil records) good caretakers of their young.
