Live Science has a story about the discovery of a dinosaur voice box. So, did T-rex sound like tweety bird? Probably not, but with the discovery of a larynx from a Pinacosaurus grangeri, we have a few clues of how they made sounds. This dinosaur was a armor plated ankylosaur that lived about 80 million years ago in what is now Mongolia. The description of the find and its implications were published in the journal Communication Biology.
The "extremely rare" discovery of an 80 million-year-old fossilized voice box that belonged to an armored dinosaur reveals that the ancient beast may have sounded more birdlike than experts previously thought, new research suggests.
Pinacosaurus grangeri — a squat, armor-plated and club-tailed ankylosaur unearthed in Mongolia in 2005 — was discovered with the first fossilized voice box (larynx) found in a non-avian dinosaur.
Now, a new analysis, published Feb. 15 in the journal Communications Biology(opens in new tab), suggests that the creature's vocalizations may have been far more subtle and melodious than its previously assumed crocodilian grunts, hisses, rumbles and roars.
