Abstract

The Yixian Formation, in Liaoning Province, northeastern China, has yielded abundant turtle remains which were described previously as Manchurochelys liaoxiensis. Study of a new collection in the Geological Museum of China and reexamination of previously studied IVPP collection allow us to assign this turtle to Ordosemys. Additional primitive features observed in Ordosemys liaoxiensis confirm its basal position among Centrocryptodira.
