Meiolaniformes


Meiolaniformes is an extinct clade of turtle relatives, defined as all taxa more closely related to Meiolania than to Cryptodira and Pleurodira. It is known from the Early Cretaceous to the Holocene of Australia, Oceania and South America. Some Eurasian taxa have been suggested to be part of the group, but this is disputed.

Taxonomy

The clade as currently defined contains the following taxa:
It has also been suggested that Mongolochelys, Sichuanchelys, and Kallokibotion from the Late Cretaceous of Mongolia, China and Europe respectively are part of this group, but other studies find these taxa in a more derived position nearer crown testidunes. Regardless, all taxa are members of Perichelydia.
