Meiolania ("Small roamer") is an extinct genus of cryptodire turtle from the Oligocene period to Holocene period, 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.
Meiolania had an unusually shaped
skull that sported many knob-like and
horn-like protrusions. Two large horns faced sideways, giving the skull a total width of 60 cm (2 ft). These same horns would have prevented the beast from withdrawing its head into its shell, however. The
tail was protected by armored 'rings' and sported thorn-like spikes at the end. The body form of
Meiolania may be viewed as having
converged towards those of dinosaurian
ankylosaurids and xenarthran
glyptodonts.
When the first fossil remains (a vertebra) was first found, and studied, it was originally thought to be a lizard, namely, a large
monitor lizard smaller than the
Megalania (
Megalania prisca, now also known as
Varanus priscus), and thus, was named accordingly. Later, when more remains were found, it was realized that the "small roamer" was actually a turtle, and not a lizard. Some synonyms of include "Miolania," and "Ceratochelys."
