In the movie scene from Jurassic World, the mid-ground shows a vast grassland with a volcano erupting in the distance. Several Tyrannosaurus rexes are chasing prey across the plains. In the foreground, there's a campsite with sofas set up on the grass, with a campfire burning in the middle. A Tyrannosaurus rex peers in, its head poking into the campsite, scanning for prey.
