"Dinosaur Fossil Unveils Surprising Bird-Like Chirping Behavior"

Paleontologists have discovered the first intact larynx bone from a dinosaur, belonging to the Pinacosaurus grangeri species. The bone suggests that some large dinosaurs, like this 16-foot-long dinosaur, may have made bird-like chirping noises instead of roaring like lions. Fossils of voice boxes are rare due to their cartilaginous composition, which usually deteriorates over time. This finding provides valuable insight into understanding dinosaur vocalizations.
