Remarks: In describing Shinisaurus crocodilurus, Ahl established the new family Shinisauridae. Subsequently, McDowell & Bogert (1954) placed it together with Xenosaurus in the New World family Xenosauridae, an arrangement which was followed by many authors (e.g., Wermuth 1969). Hu, Jiang & Zhao (1984) revalidated Shinisauridae, and Böhme's (1988) results supported this by demonstrating that the two genera are not related to each other.

Distribution:  As for the single genus of the family, Xenosaurus.
