The bone is the first example of a larynx in reptilian dinosaurs that paleontologists have ever found. Based on a fossil from a Pinacosaurus grangeri, paleontologists think that some large dinosaurs might have chirped like birds, not roared like lions. The fossil is the first intact larynx bone from a dinosaur ever found, the scientists said in their study which was published in the journal Nature earlier this year. How they found the bone and discovered its purposeA scan of the fossilized larynx of the Ankylosaurus dinosaur Pinacosaurus grangeri. They initially thought the bone they found was used in a different part of the dinosaur's throat, for breathing, Yoshida said.
