One species of the Pliocene of Antwerp, Oncocottus asper, now is iden.tified as Enchelyopus. The otolith faunas from Sylt are strongly dominated by the Gadidae and clearly show their own character; nevertheless they exhibit a much closer relationshlp with older Late Miocene faunas and even with Middle Miocene faunas than with the Pliocene to recent ones which are known from the North Sea Basin. The Syltian clays were formed in a quiet, open marine environment not very close to the coast, probably at depths between 50 and 100 m.
