A new report suggests that dinosaurs never emitted the loud, frightening roar so many believe they did, but instead, may have mumbled with their mouths closed, according to Futurity.

Research published in the journal “Evolution” looks at how some birds make sound through closed-mouth vocalization, which are sounds produced through the skin around the neck when the beak remains closed, such as the coo of a dove, reports Futurity.

Researchers found that 52 out of 208 bird species use closed-mouth vocalization, and that the vocalization has evolved 16 times in archosaurs, which includes birds, crocodiles and dinosaurs, says Futurity.

Scientists say closed-mouth vocalization across birds and crocodiles -- living archosaurs -- shows that the communication can occur among all species of archosaurs.
