Dinosaurs didn't roar. They cooed, according to scientists
Chad Eliason thinks we have the wrong idea about the dinosaur's roar.
Eliason says the evidence suggests otherwise. "We know now that birds are essentially these flying dinosaurs. So I think we need to reframe our thinking and see how are birds and their relatives, crocodiles, producing these sounds to really understand potentially how dinosaurs did it."
Eliason's team analyzed closed-mouth vocalizations among a number of birds and other reptilian groups in their research that is published in the August print issue of the journal, Evolution.
"You can imagine the coo of a dove. We think that these coos or these booms or these low frequency hooting sounds may have been possible as these dinosaurs were showing off to a nearby female or communicating to a nearby animal."
