Ctenognathichthys is an extinct genus of prehistoric marine ray-finned fish that lived during the Middle Triassic epoch of Europe, in the former Tethys Ocean. [1] [2]
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]
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]
It was a small fish measuring 21 cm (8.3 in) in total length. [9] It had long prehensile teeth in its upper and lower jaws. [3]
