"Dinosaur Chirping: Evidence Found in Ancient Throat Bone"

Paleontologists have discovered the first intact larynx bone from a dinosaur, belonging to the Pinacosaurus grangeri species. The bone suggests that some large dinosaurs may have made bird-like chirping noises instead of roaring like lions. Fossils from voice boxes are rare due to the cartilage composition, and previous findings have only been from birds. This discovery provides insight into understanding dinosaur vocalizations.
