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). [1] [2] The type and only species, B. macrognathus, is known from a single partially complete skull (ca. 80 millimetres (3.1 in) long), [3] which was recovered from the Pedra de Fogo Formation near Pastos Bons, Maranhão, Brazil. [1]
Brazilichthys is referred to its own family, Brazilichthyidae [3] ( monotypy). Its evolutionary relationships to other genera are not well known. It was hypothesized that Brazilichthys could be closely related to the Triassic Birgeria, [4] though this was subsequently considered unlikely. [1]
