Diagnosis
ReferenceDiagnosis
D. B. Brinkman et al. 2013A “macrobaenid” differing from all other Early Cretaceous “macrobaenids” from Asia in being round in outline and in retaining well-developed costal-peripheral fenestrae in individuals of large size. Similar to Liaochelys, Manchurochelys, Ordosemys, and Dracochelys and differing from Kirgizemys and Wuguia in that surface of carapace is smooth, without plications extending posterior to the sulci. Similar to Manchurochelys, Kirgizemys, Wuguia, and Dracochelys and differing from Liaochelys and Ordosemys in that the vertebral scutes 2–4 are narrow. Skull similar to Dracochelys, Liaochelys, and Kirgizemys and differing from Manchurochelys and Ordosemys in that prefrontals contact one another at the mid-line. Differing from Dracochelys in that carapace does not have a tapered posterior end
