Meiolania ("Small roamer") is an extinct genus of cryptoire turtle from the Oligocene to Holocene, with the last relic populations at New Caledonia which survived until 2000 years ago. It was huge, measuring 2.5 m (8 ft 4 inches) in length, making it the largest known nonmarine turtle or tortoise. It lived in Australia and New Caledonia and fed on plants. Its surviving relatives are the cryptodire turtles of South America. The Meiolania specimens which were once living on New Caledonia and Lord Howe Island were much smaller than their giant relatives from the Australian continent.
