This fossil teleost fish was initially assigned to <em>Pholidophorus</em>, a genus that recently received an emended diagnosis (Arratia, 2013). The cranial characters of <em>L. friedeni</em> considerably differ from those that now define <em>Pholidophorus</em> and the Pholidophoridae, excluding its attribution to both this genus and this family. In <em>L. friedeni</em> the posttemporal fossa is completely located on the lateral face of the braincase and not on the rear of the skull as usual. Such a position is unique among “Pholidophoriformes” and justifies the peculiar generic status of this taxon. <em>L. friedeni</em> possesses three specialized characters (a beryciform foramen piercing the anterior ceratohyal, arcocentra associated to the chordacentra and ovoid scales devoid of the peg-and-socket system) suggesting it occupies a position crownward of most “pholidophoriforms”, closer to Jurassic and younger teleosts with cycloid scales.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Osteology and relationships of <i>Luxembourgichthys (\"Pholidophorus\") friedeni</i> gen. nov.
