Discussion Paratrisopterus glaber differs from the Middle Miocene species P. brinki (Posthumus, 1923) in its more compressed shape and relatively smooth outer face. It is, however, not as compressed as the rare Middle Miocene P. globosus (Posthumus, 1923) . Paratrisopterus glaber was described from the Late Miocene of the North Sea Basin but was apparently more widely distributed in the European seas. It has recently been recorded from the Zanclean and Piacenzian of Spain, where it occurs in parallel with P. labiatus (Schubert, 1905) in the Zanclean. Te occurrence in the Moroccan Early Pliocene fills a geographic gap in the distribution. Otoliths have been described in situ by Landini and Sorbini (1999) from a fish interpreted as Gadiculus labiatus from the Early Pleistocene of Italy. According to the otoliths figured in this article, the species represents P. glaber .
