Shinisauridae is a family of anguimorph lizards whose only living representative is the Chinese crocodile lizard (Shinisaurus crocodilurus) from China and Vietnam, but which also includes the extinct genus Bahndwivici from the Eocene Green River Formation of Wyoming in the United States.[1][2][3]


Shinisauridae was once categorized within Xenosauridae,[4] but most recent studies of the evolutionary relationships of anguimorphs consider Shinisaurus to be more closely related to monitor lizards and helodermatids than to Xenosaurus.[5]

Two subspecies within Shinisaurus are recognized:[6][7]

  • Shinisaurus crocodilurus crocodilurus Ahl, 1930 (southeast China)
  • Shinisaurus crocodilurus vietnamensis Schingen et al., 2016Vietnamese crocodile lizard (northeast Vietnam)
