cages cannot hold them

You can see various kinds of dinosaurs closed in the cages. The camera is moving forward in the corridor between those cages. The dinosaurs seem angry. Every dinosaur screaming and going aggressive. They seem like they're trying to destroy the cage and destroy the one who is behind the camera lens. The whole scene seems very scary. You can see some details like the saliva from their mouths, the tooths, the nails, the proper anatomy and realistic skin of those dangerous predators.
