Taxonomy and occurrence
It contains a single species, C. bellottii from the Anisian–Ladinian-aged Besano Formation of Monte San Giorgio area (Swiss-Italian borderland),[3] the early Ladinian Prosanto Formation of canton Graubünden, Switzerland, and possibly the late Ladinian Alcover Unit of Spain.[2][4][5] Indeterminate remains are known from the middle Anisian of the Strelovec Formation of Slovenia.[6] A second species (C. hattichi Bürgin & Herzog 2002) from the Prosanto Formation was previously placed in this genus, but a 2009 study placed it in the new genus Luopingichthys alongside a species from China.[7]
Classification
Ctenognathichthys was first classified as a member of the family Perleididae and order Perleidiformes, a group that is now considered paraphyletic.[3] More recently, it has been reclassified into the family Louwoichthyidae (order Louwoichthyiformes).[8]
