Fisch-Otolithen aus dem Pliozän von Antwerpen (Belgien) und Ouwerkerk (Niederlande) und aus dem Plio-Pleistozän der Westerschelde (Niederlande)

53 species are listed from the Pliocene of Antwerp (Belgium) and a boring at Ouwerkerk (Netherlands) and from the Pliocene and Pleistocene of the West Scheldt (Netherlands; a few dredged specimens). Only five were previously known from Antwerp. Descriptions of 13 new species: Trisopterus elongatus, T. pliocenicus, Micromesistius hochti, Melanogrammus conjunctus, Trachinus angustus. Otophidium compactum. Ammodytes rostratus, Gobius ornatus, (Gobiidarum) modestus, (G.) dorsoconcavus, (G.) bicornutus, (G.) rectangularis and Oncocottus asper, and three new subspecies: Gadichthys benedeni verticalis, Carapus nuntius elongatus and Ammodytes lanceolatus sculptus, are given. Within the family of the Gadidae three new genera are established, Colliolus, Gadichthys and Palaeomorrhua, as the first stage of a necessary revision of this family. A provisional family tree is set up. The Pliocene faunas of bony fishes exhibit a closer relationship with the recent one of the North Sea than with what is known from the Miocene. The Pliocene deposits of Antwerp were formed in a shallow marine environment close to the coast, whereas the faunas of bony fishes from the Pliocene of the Ouwerkerk borehole preferred a somewhat deeper sea on the shelf.
