Giants of the Mesozoic

Stand beneath some of the world's largest dinosaurs as you enter this snapshot of life in prehistoric Patagonia (145-165 million years ago). Take in a scene of an epic dinosaur battle between Giganotosaurus and Argentinosaurus with a flock of pterosaurs scattering away.

Play the role of a paleontologist as you examine the terrain to discover buried and trace fossils of other plant and animal species, such as dinosaur tracks, an Araucaria tree, a crocodile and a turtle shell.*
