"We believe that these dinosaurs were very communicative. They even produced and perceived low-frequency sounds like those made by elephants, which travel several kilometers and are imperceptible to humans," says palaeobiologist Angel Alejandro Ramirez.
“We know that they had ears with the ability to receive low-frequency sounds, so they must have been peaceful but talkative dinosaurs. Some paleontologists theorize that they emitted loud sounds to scare off carnivores or for reproduction purposes, which suggests that the crests wore bright colors,” said Ramirez.
