Do you listen that sound ? It ’s 65 million years ago and there ’s a dinosaur calling out through the wilds . But it ’s not a holler . or else Modern enquiry says that phone would likely be better described as a “ coo ” or a “ mumble . ”
Researchers from the University of Texas did a comprehensive review of the vocal organs of shuttle and the kinds of sounds they made . Then they play off those up with the vocal organs come up in fossilised dinosaurs for apaper come out next monthin Evolution . The solvent , they say , suggest that many dinosaur were far more likely to vocalize with a closed - mouth — perhaps , a disapproving “ hmm ” or a more pensive “ umm”—than with a full - throated boom .
This is far from the only finding paleontologists have adopt from the birds . Feathers are replacing scale more and more often in our dinosaur drawings . A group of scientists recently stick a prosthetic tail on a chicken to make it mime the pace of a bipedal dinosaur .

Some may say that this comparison diminish the awe-inspiring force of the dinosaur , but the truth is that it only makes them all the more terrific .
Still do n’t think a coo sound so intimidating ? Well , heed to this :
Now imagine that Struthio camelus suddenly 60 feet tall and stepping right through that fencing like it was n’t even there .
“ What is it doing ? ” asks the unnamed videographer in the clip — moment before it becomes unsettlingly clear just what the Struthio camelus is doing . It ’s teaching you the true meaning of fear .
