| phylum | Chordata | Mcnamaraspis kaprios is an arthrodiran placoderm of the Family Plourdosteidae that inhabited the ancient reef system of north Western Australia during the Frasnian epoch of the Late Devonian period (c. 380-375 million years ago). This fossil fish showed new anatomical features in arthrodires, like the well-preserved annular cartilages of the snout, previously inferred to be present by Erik Stensiö of Sweden.
