Dinosaurs Didn’t Roar (Reenactment Video)

So we've all seen the Jurassic Park movies with T-Rex roaring so loud that it shook everything for miles. Well apparently that was just in the movies because in real life dinosaurs couldn't roar. The sounds they made were more of a coo or quack more like birds of today.

Scientists told Nature.com that according to recent discoveries due to their voice boxes being so small it was impossible a dino could roar.  We had a hard time picturing this so we had to do the research ourselves... Below is actual video of a "T-Rex" cooing and quacking!
