Amazichthys is an extinct genus of selenosteid arthrodire from the Middle Famennian of the Late Devonian of the Anti-Atlas Mountains of Morocco. It contains a single species, Amazichthys trinajsticae. It is one of a few example of placoderm known from whole body shape, including cartilaginous axial and fin elements.[1]

Description[edit]

Amazichthys had a profile similar to that of fast-moving pelagic fishes, with lateral keels for stability, and a lunate caudal fin, suggesting it could reach and maintain high speed.[1] The holotype, AA.MEM.DS.8, is 89.7 cm (35.3 in) long.[1][2]

Etymology[edit]

Amazichthys trinajsticae was named after the North African ethnic group Amazigh (Berbers), and Australian palaeontologist Kate Trinajstic.[1]

Taxonomy[edit]

Amazichthys is part of Selenosteidae, a family inside the clade Aspinothoracidi, inside of Pachyosteomorphi, along with Dunkleosteoidea.

The cladogram shown here is based on Jobbins et al, 2022.[1]
