Travel back in time at the Giants of Mesozoic exhibit, set in Patagonia, Argentina. Skeletal casts of the four-legged, long-necked Argentinosaurus, the largest known dinosaur measuring at 123-feet long, and a Giganotaurus, the largest known meat-eating dinosaur which stood on two feet at a mere 47-feet long, are locked in battle while Pterodaustros and Anhangueras fly overhead. The Dinosaur Gallery has life-sized models and murals of the ancient reptiles that once roamed what is now Georgia, and outside at Dinosaur Plaza are bronze statues depicting a family of Laphorhothon atopus which look similar to Ducky in the Land Before Time cartoons.
