@smile_5888: Immersive dinosaur sounds! Click carefully! The dinosaur calls are inferred by scientists based on the calls of fossils and modern birds. Since dinosaurs are extinct, we cannot hear their calls directly. However, some scientists believe that large dinosaurs may have made low roars, while small dinosaurs may have made shrill calls. These speculations are mainly based on the restored models of the dinosaurs' respiratory system and vocal cord structure. Of course, the exact nature of these sounds remains a mystery. #giantphobia #dinosaurscience #JurassicWorld #DinosaurAge #dinosaurextinction
