Chelidae

The Chelidae are one of three living families of the turtle suborder Pleurodira and are commonly called the Austro-South American side-neck turtles. The family is distributed in Australia, New Guinea, parts of Indonesia, and throughout most of South America. It is a large family of turtles with a significant fossil history dating back to the Cretaceous. The family is entirely Gondwanan in origin, with no members found outside of Gondwana, either in the present day or as a fossil.
