Ancient Monsters: Stegosaurus and Allosaurus

After the T-Rex area one can turn around and encounter two other dinosaurs. One is Stegosaurus from the late Jurassic period: 155-150 million years ago:

Right next to Stegosaurus is Allosaurus that lived at the same time:From above:In the video I show a few other things. One is this exhibit about dinosaur sounds and Corythosaurus and Parasaurolophus. I mentioned last time no one knows what dinosaurs sounded like, but scientists think they have some ideas about these two creatures. This has to do with the way the "horns" on their heads were shaped. Watch the video for the computer simulation at the end about this.
