Amakusaichthys is an extinct genus of ichthyodectiform fish which lived during the Late Cretaceous, known from only one species A. goshouraensis. Fossils are known from Kumamoto Prefecture in Japan.^[1]

Discovery

Fossils were discovered in 2012 from construction site in Goshoura, Amakusa.^[2] This site is later considered to belong to Hinoshima Formation of the Himenoura Group.^[1] It was the first discovery of marine ichthyodectform fish described from Asia in detail, while other ichthyodectiform fish from Asia (three genera belong to Chuhsiungichthyidae) are from non-marine environment.^[1]^[2]

Description

Amakusaichthys is relatively small ichthyodectiform fish with length around 60 cm (24 in). It is characterized by its long snout and small mouth and teeth.^[1] Multiple specimens are found overlapped in one place, suggesting its schooling ecology.^[2]^[3]

Classification

Amakusaichthys was not assigned to any family in original description. However, characters suggested that it was related to Heckelichthys .^[1] In 2021, it was assigned to Bardackichthyidae, alongside Heckelichthys and Bardackichthys .^[4]
