Brazilichthys
Brazilichthys is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Cisuralian (early Permian) epoch in what is now Maranhão, Brazil (Parnaíba Basin).
The type and only species, B. macrognathus, is known from a single partially complete skull (ca. 80 millimetres (3.1 in) long), which was recovered from the Pedra de Fogo Formation near Pastos Bons, Maranhão, Brazil.

Classification
Brazilichthys is referred to its own family, Brazilichthyidae (monotypy). Its evolutionary relationships to other genera are not well known. It was hypothesized that Brazilichthys could be closely related to the Triassic Birgeria, though this was subsequently considered unlikely.
