Eoeugnathus (Greek for "dawn true-jaw") is an extinct genus of prehistoric marine ray-finned fish belonging to the Halecomorphi.[1] Eoeugnathus existed during the Middle Triassic in what is now Europe.[2][3]
It contains two species:[4][5]
- E. bellottii (Rueppel, 1857) - Ladinian of Italy and Switzerland (Meride Formation, Perledo-Varenna Formation) (=Allolepidotus bellottii Rueppel, 1857)[5]
- E. megalepis Brough, 1939 (type species) - latest Anisian to late Ladinian of Italy (Besano Formation), Switzerland (Prosanto Formation), and Spain (Muschelkalk)[3]
It was initially placed in the Caturidae and then the Panxianichthyiformes[6], but more recent studies have placed it in the new ionoscopiform family Subortichthyidae.[5][7]
