Neotype: MNHN 8903, incomplete skull (chosen by Blainville, see Vignaud, 1995).

Note: The correct spelling is M. superciliosus , not M. superciliosum . Lydekker (1890b) amended the epithet based on the neuter suffix, rather than retaining the masculine suffix (i.e. - sum instead of - sus). In accordance with the code of the ICZN, Article 30.1.3, the gender of the generic and epithet name must match, and as Metriorhynchus is masculine (- rhynchus is the Latinized form of the Ancient Greek - rhynchos) - sus is the correct suffix.
