Description
Genus Notoberyx gen. nov.
Type species. Notoberyx cionei sp. nov.
Etymology. From notos (Greek) = southern winds, and the genus name Beryx, referring to the southern occurrence of the type species.
Diagnosis. Very high-bodied otoliths with a ratio OL:OH between 0.7 and 0.85. Dorsal rim expanded across entire length. Ventral rim deep. Rostrum short, blunt, not much extending beyond level of antirostrum. Ostium short, narrow, only slightly widened ventrally. Cauda long, distinctly turned upwards towards its tip. CaL:OsL = 1.3—1.7.
Remarks. The general appearance of Notoberyx is typical for trachichthyid otoliths with the deep ventral rim and the upward bent cauda. They are, however, readily distinguished from the many other otolith-based genera of the family known from the Late Cretaceous and Palaeogene by the high body and the short and narrow ostium combined with a short rostrum.
Included species. The type species N. cionei sp. nov. described below from the Eocene of Antarctica, and N. madseni (Schwarzhans, 2007), originally described as ‘genus Caproidarum ’ madseni from the early Eocene of Denmark.
