†M. manchoukuoensis Endo & Shikama, 1942

Manchurochelys was first named by Endo and Shikama in 1942, and contains the single species, M. manchoukuoensis (sometimes misspelled M. manchouensis). A second species, M. liaoxensis, was named in 1995 but was later shown to be a species of Ordosemys.[4] Manchurochelys was a relative of the modern-day snapping turtle.[5] It has been occasionally placed in the family Sinemydidae, although it is said to more likely belong in the family Macrobaenidae.[6]
