Brazilichthys is an extinct genus of prehistoric ray-finned fish that lived during the Cisuralian (early Permian) epoch in what is now Maranhão, Brazil (Parnaíba Basin).[1] The type and only species, B. macrognathus, is known from a single skull (ca. 80 millimetres (3.1 in) long),[2] which was recovered from the Pedra de Fogo Formation.[1]

Classification

Brazilichthys is referred to its own family, Brazilichthyidae[2] (monotypy). Its evolutionary relationships to other genera are not well known. It was hypothesized that Brazilichthys could be closely related to the Triassic Birgeria,[3] though this was subsequently considered unlikely.[1]
