The Giant Tortoise, specifically Meiolania, is a large aquatic freshwater turtle from the Ice Age. It features in Zoo Tycoon: Dinosaur Digs, and makes pig-like snorting sounds. Meolania can swim underwater. It is the second largest land-dwelling chelonian of all time, the only bigger one being the nearly cow-sized Megalochelys.
The giant tortoise's favourite foliage is Arctic grass.
It prefers snow and fresh water.
- Despite being depicted as tundra dwelling reptile in Zoo Tycoon, the "giant tortoise" actually lived in warmer habitats, as prehistoric Australia (where it lived) had a sub-tropical climate (although New Zealand species probably could tolerate cold climates.)
