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]
Taxonomy and occurrence
[edit]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
[edit]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]
Description
[edit]
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]
