Manchurochelys
''Manchurochelys'' is an extinct genus of turtle in the order Paracryptodira. It existed during the early Cretaceous of what is now northeast China.〔''Chinese Fossil Vertebrates'' by Spencer G. Lucas. Retrieved on 2008-08-24.〕 It has been found in the Jianshangou Bed of West Liaoning's Yixian Formation.〔(Jianshangou Bed of the Yixian Formation in West Liaoning, China; ) Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, 2004-02-06. Retrieved on 2008-08-25.〕 However, it is a rarely found fossil.
''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''.〔Tong, H., Ji, S. and Ji, Q. (2004). "(''Ordosemys'' (Testudines, Cryptodira) from the Yixian Formation of Liaoning Province, northeastern China: new specimens and systematic revision. )" American Museum Novitates, 3438: 1-20.〕 ''Manchurochelys'' was a relative of the modern-day snapping turtle.〔''Dinosaurs: Photo Captions'' by the American Museum of Natural History. ()〕 It has been occasionally placed in the family Sinemydidae, although it is said to more likely belong in the family Macrobaenidae.〔(Fossil Turtle Newsletter. ) Retrieved on 2008-08-26.〕
