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]
Classification
[edit]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]
